The use of
chemistry in daily life
Did
you know that the role of chemistry is quite a lot for human life? Currently
the development of chemistry is very rapid and has given influence in human
life in the form of influence both good and bad influence. Many products
currently use chemicals that actually have a detrimental effect on humans
themselves such as dyes on ready-to-eat foods. There are also good effects such
as NaCl which is a chemical salt to add flavor in cooking ..
Before
knowing further the role of chemistry further, acquainted with chemistry feels
absolutely no harm. Chemistry is a branch of natural science that studies the
properties, structures, composition, and changes of matter, and the energy that
accompanies material change.
Without us realizing that in fact most of the things
we do in life are related to chemistry. Matters related to food, clothing,
fuel, medicine, building construction materials, electronic industry materials,
and products involving chemistry. Therefore, the role of chemistry is felt in
life and various fields of scientific study.
But
not everyone has a good view of chemistry. What's more related to food. Most of
them think chemistry is dangerous. They do not realize that there are also many
chemicals that bring benefits in daily life.
The following are chemicals that are usually present
in a community home:
A. Cleaning Chemicals
In
everyday life, we recognize a variety of cleaning chemicals, including soaps
and detergents, soaps and detergents can make fats and oils that were not mixed
with water to be easily mixed. Soap and detergent in water can release a type
of ion that has a water-like part (hydrophilic) so that it can dissolve in
water and water-dislikes (hydrophobic) parts that dissolve in oil or fat. If in
clothes is washed with detergent there is fat impurities then the hydrophobic
ion part enter into fat or oil granules and the hydrophilic ion part will lead
to the water solvent. This situation causes oil granules to reject each other
because it becomes a similar charge. As a result, fat or oil impurities that
have been released from clothing can not be united again and remain in
solution.
B. Cloth bleach
Bleach
solutions sold on the market usually contain sodium hypochlorite (NaOCl) active
ingredients of about 5%. Besides being used as bleach and cleaning stains, it
is also used for disinfecting (disinfecti
C. Fragrance
Fragrance
is another chemical that is closely related to our daily life. We can obtain
deodorant from both natural and synthetic materials. In addition to substances
that give rise to scented fragrances, fragrances sold on the market usually
contain other substances, such as alcohols for liquid perfumes and alum for
dense in formers. In addition to alcohol, there are still a variety of other
additives that are deliberately added to the perfume so that the perfume is
easily sprayed (the substance serves as propellant). Among the additives that
can serve as propellants there are those that can pollute the environment.
D. Pesticide
Pesticide-type
chemicals are closely related to the lives of farmers. Pesticides are used to
eradicate plant pests so as not to disrupt agricultural production. Pesticides
include all types of drugs (substances / chemicals) pesticides that are
intended to protect plants from insect, fungal, bacterial, viral, mouse, snail,
and nematode (worms) attacks.
Pesticides commonly used by farmers can be
classified according to the function and target of its use, namely:
·
Insecticides, ie pesticides used to
eradicate insects, such as grasshoppers, ladybirds, aphis, and caterpillars.
·
Fungicides, ie pesticides used to
eradicate and prevent the growth of mold or fungus.
·
Bakterisida, namely pesticides to
eradicate bacteria or viruses.
·
Rodenticides, ie pesticides used to
eradicate plant pests in the form of rodents, such as rodents.
·
Nematisida, namely pesticides used to
eradicate worm plant pests (nematodes).
·
Herbicides, ie pesticides used to
eradicate weeds (weeds), such as reeds, grasses, and water hyacinths.

That's a quick explanation of the materials used each day that the other contains chemicals.
Try to give examples of dangerous chemicals contained in food.
BalasHapus1. Monosodium Glutamate Flavor (MSG)
HapusThere are many forms, types or kinds of flavor enhancers or flavor enhancers other than MSG. Monosodium glutamate and similar flavor-like substances we call it as micin, vetsin, and others. MSG is commonly used by housewives, food stalls, restaurants and others to make food taste more pronounced by stimulating the tongue with certain chemicals. If given to experimental animals, the animals will degenerate and nekrosi cells of neurons and nerve cells lining the eye's retina, cell mutations, colon cancer, liver cancer, brain cancer, kidney cancer and fat tissue destruction. In the past, people who consumed large amounts of msg had chinese restaurant syndrome.
2. Coloring Substances Textile Materials, Paint, Paper, Animal Leather, etc.
Usually the producers of dangerous food and beverages want to produce food and beverages at very low cost in order to generate large profits and can set a cheap price to consumers. Some manufacturers prefer to use harmful dyes for their own consumers. Artificial chemical dyes such as rhodamine-b, methanil yellow, borax, and others. Borax is a corpse preservative that can provide color to the food. If these harmful dyes are given to unfortunate experimental animals, they can cause lymphoma. In humans may be able to cause cancer that is dangerous and deadly.
3. Saccharin Sweetener (Saccharin) and Cyclamate (Cyclamate)
Saccharin is a white crystalline powder that tastes very sweet on the human tongue. Saccharin is usually not as flavorful as sugar and sugar cubes. If measured, the saccharin sweetness 550 times sweeter than regular sugar. By wearing saccharin, food and beverage traders can make big profits because they do not need expensive sugar. An experimental animal will be able to develop bladder mucosal cancer if it consumes saccharin in certain levels on a regular basis.
Cyclamate is a white crystalline powder like saccharine but its sweetness level is only 30 times that of ordinary sugar. In European countries and in the United States has banned cyclamate as a sweetener of human food and drink. If silkamat is given to the leukocyte culture medium and the human monolayer will be able to cause the cell chromosome to break.
Please give me an example of pesticides?
BalasHapusNematicides
HapusNematisida is a poison used to eradicate the disruptive body in the form of a worm - a parasitic worm that usually attacks the roots of plants. Example: Furadan 3 G.
Herbicide
Herbicides are pesticides to prevent and kill weeds or pests, such as water hyacinth, weeds, and reeds. Imperata can be regarded as plant pests because Imperata absorbs all the food substances present in the soil. Example: Ronstar ODS 5/5 Saturn D.
Fungicide
Fungicides are pesticides to combat fungi (fungi). Example: Rabcide 50 WP, Kasumin 20 AB, Fujiwan 400 EC, Daconil 75 WP, Dalsene MX 2000.
What kind of pesticide is used to eradicate mice? how to use?
BalasHapusRodenticide, a pesticide used to eradicate plant pests in the form of rodents, such as rodents. Rodenticides are used by mixing them with rats' favorite foods. In putting the bait must be careful, not to be consumed by other animals. An example of this type of pesticide is warangan.
Hapuswhat the negative effect of chemistry in cloth bleach?
BalasHapusBleach is often used in clothing. Bleaching materials can be differentiated into two kinds, namely bleach clothing and skin whitening. The most commonly used bleach chemicals are sodium hypochlorite (NaClO). Chemical if it is mixed with detergent it will produce chlorine gas which if inhaled will be irritating at tenggrokan and respiratory system
HapusPaper made from chemicals. Which I ask, dangerous if the fried (cake) we wrap with paper?
BalasHapusThe paper used is usually based on ONP and OCC. The dangers lurking behind the food wrappers made from ONP and OCC are real. LIPI research results prove that the content of bacteria in rice paper made from recycled paper is as much as 1.5 million colonies / grams. Prior to processing at the factory, ONP and OCC are piled in open areas exposed to direct sun, dust, dirt, to rainwater.
HapusPlease provide another example of Chemical Benefits in Science and Technology (Science and Technology)?
BalasHapusApplication of chemistry in Science and Technology (IPTEK) requires consideration that has an influence on the development process of science and technology. Responsibility is an important concern regarding the activities and use of science and technology. In this case means Science and Technology must pay attention to human nature and dignity, maintain the balance of the system and be responsible for the public interest. Natural Science is a reflexive form (reflexion form) of the learning process that exists in the structure of action of instrumentation, the action aimed at controlling the external conditions of human beings. Natural Science is concerned with interests in predicting and controlling natural processes.
HapusIPA is divided into several classes. In the science of IPA starting from Mathematics, Astronomy, Physics, Chemistry, Biology and Sociology. Where the classification is based on the order of grading, the principle of dependence and the size of simplicity.
Science and Technology As we know, technology has now entered the lives of most humans even from the upper to lower class even though the effort is a way or way in realizing the welfare and increase the dignity of humanity. On the basis of creativity, human reason to develop science and technology in The order to process the natural resources provided by God Almighty.Where in the development of science and technology should be based on morality and humanity that is just and civilized, so that all people denounce science and technology evenly. On the one hand there has been a very good development in telecommunications aspect, but the implementation Development of science and technology is still uneven. There are still many underprivileged people who are desperate to get the knowledge and technology tersebut.Hal it is because of the high cost of education that they have responsibility.Therefore, the government needs to address and respond to these problems, for the role of science and technology can aim to improve Human Resources The development of science and technology useful for the advancement of life of Indonesia also has a negative impact. Things to note in the application of science and technology to minimize its impact to a minimum,
Genetics, medicine, neurology, pharmacology, botany, climatology, meteorology, toxicology, psychology, paleontology, geology, cosmology, electronics, matalurgi, archeology, ecology.
BalasHapusWhy chemical reactions can occur where in the world life?
Kimi's reaction is always there in life. Because almost all human activities are related to chemistry.
HapusLet's look at some examples that involve chemical reactions, and are an integral part of our being.
Human Body Composition
About 96% of our body mass consists of only 4 elements: - Oxygen, Carbon, Hydrogen and Nitrogen. The remaining 3% consists of about 60 elements including sodium, potassium, calcium, zinc etc.
The elements required in larger quantities are called macro-nutrients and others, usually in parts per million or less, called micro-nutrients. Chemical reactions, the human body consists of water and elements such as organic carbohydrates, proteins, lipids and nucleic acids.
Metabolism
Organic processes that occur in the human body are called metabolism, which involves a large number of chemical reactions. Enzymes secreted by different organs act as biocatalysts that accelerate the rate of reaction, while the hormone regulates time and speed.
Our wellbeing, smooth function and normal health depend on metabolic processes. The coordination and simultaneous occurrence of this process of life in an orderly manner is the reason we are fit, healthy and alive.
Respiration
Breathing is the exchange of gases between the organism and its environment. Respiration is a chemical reaction process, which is a reaction between glucose or sugar with oxygen, which releases energy.
This is the process by which inhaling oxygen from the air causes lung inflation and then deflation occurs by exhaling carbon dioxide into the environment. Reactions that occur during breathing: -
C6H12O6 + 6O2 ➜ 6CO2 + 6H2O + Energy
Water Composition
Water is the elixir of life on Earth. Hydrogen is a highly flammable gas and oxygen is a gas that is unlikely to react without burning, to each other forming a covalent bond to create the most effective fire extinguisher called water.
The chemical reaction formula of water is H2O. Yes! We drink everyday chemical reactions. Water is very important for all metabolic processes that occur in our body. As Leonardo da Vinci states "Water is the driving force of the whole world."
Feeling hungry
When you feel hungry ghrelin hormone is secreted by the stomach that triggers hunger. It stimulates the release of growth hormone. It plays a role in insulin release and protection of cardiovascular organs. More ghrelin is produced thus increasing your desire for food.
What is the meaning of propellant ?
BalasHapusThe propellant is the chemicals used in the production of energy and pressurized gas used to create fluid movement or to produce propulsion vehicles or other objects or projectiles. Common propellant is energetic and consists of a fuel, such as gasoline, jet fuel, rocket fuel, and oxidizing agents. The propellant that burn or decompose to produce gaseous propellant. The other propellant liquid can evaporate.
HapusHow the negatife impact of chemical in the cloth bleach?
BalasHapusBleaching (bleaching agent) are chemicals that can be used to treat stubborn dirt on clothes. The active ingredients contained in clothing bleach, include sodium hypochlorite or sodium perchlorate.
HapusHowever, excessive and excessive bleaching may cause rapid wear to wear. This is because the active ingredient can damage the particles and fabric fibers.
Excessive use of bleach and too often causes cloth seratserat to become hard and brittle. So that clothes do not quickly damaged then you should use bleach only when needed only.
Bleach should only be used if regular detergent use is not able to remove impurities cleanly. Keep in mind, clothing bleach can lead to waning colors on colored clothing.
Excessive use of bleach can also cause environmental pollution. Active substances in bleach may kill bacteria in the soil. How to overcome the waste of bleach is almost the same with soap waste and detergent management.
Side Effects of Bleach Usage
The use of excessive bleach in addition to causing damage also has a negative impact on the environment. If waste water containing bleach discharged to the ground or into streams can cause water contamination.
In addition, in bleach is contained active substances and materials that are corrosive that can kill beneficial bacteria in the soil. As a result, soil fertility can be disrupted.
More extensive waste disposal containing bleach will lead to new environmental pollution. Especially for facial bleach offered through advertising, we must be careful in choosing and using it.
This is because some facial and body bleach products are shown to contain heavy metals mercury (mercury). Bleach containing mercury if used continuously can be as toxic in the body and can cause cancer (carcinogenic).
What threats posed if the food we eat contains pepticides?
BalasHapusVegetables and fruits are the healthiest foods the body needs. High-fiber vegetables and fruits can facilitate the body's metabolism, besides vegetables and fruits also contain many vitamins essential for the formation of body tissues and strengthen the function of organs. However, without us knowing it, vegetables and fruits can contain harmful substances.
HapusThe food we eat, especially fresh fruits and vegetables, contains pesticide residues. Although not directly, the dangers it produces have long-term effects, such as cancer, tumors and other chronic diseases. The impact of pesticide use on food is not only on humans, but also has an active role in destroying the ecology of the environment. Among others, groundwater contamination and changes in the hormone system of mammals and fish. So, not only vegetables and fruits, fish and livestock that we consume can also contaminated with pesticides.
What compounds are contained in soaps and detergents that can make fats and oils that are not mixed with water to mix easily.
BalasHapusComposing detergent
HapusSurfactant
The most important ingredient in detergent is the job of removing stains from your shirt. The surfactant is divided into 3 types, ie cationic (positively charged, unreacted in aqueous water), anionic (negative ions, reacting with water, containing magnesium and calcium), and nonionic (cleaning oil stains).
Builder
Improve the quality of detergent leaching and prevent the solution from becoming too alkaline.
Sodium silicate
