EXAMPLE OF CHEMICAL USE IN A DAILY LIFE

Chemistry is a science related to daily life or natural phenomena, because starting from the affairs of food and clothing, fuel, medicine to building construction materials, electronic industry materials and products involving chemistry chemistry. What distinguishes chemistry from other sciences is, Chemistry specializes in the structure, structure, properties and changes of matter, and the energy that accompanies material change

In addition, chemistry is a stepping stone in order to learn other science. Like, we must understand about atoms in chemistry in order to understand the magnetic force in physics. Or, we can not learn about photosynthesis in biology if we do not understand the basic reactions involved

Chemistry in everyday life is everywhere, everything we feel, we smell, we taste is chemistry. When you cry chemical reactions occur, when you are hungry chemical reactions occur, so studying chemistry is very important to know about what really happened in this world

Most people misunderstand chemistry, this needs to be straightened out. They assume that chemistry exists only in the laboratory, chemistry is only in the diet. Though experts believe that everything in Nature is chemistry

1. Adding Salt To Make Coffee Sense Better

Have we ever ordered or made coffee and it tastes so sour? One ingenious solution to the sour coffee taste is to sprinkle it with a pinch of salt. Salt dissolves in coffee to release sodium ions. Coffee will not change better, but it will taste better because sodium blocks the taste receptors that detect the bitter. If we brew your own coffee, we can add salt during the coffee-making process. Another way to reduce bitterness is to avoid making a coffee solution with super-hot water. Too much heat during brewing increases the extraction of a bitter-tasting molecule

2. Cleaners

What do my friends all feel when they have finished doing sports activities, such as running, football, playing basketball or volleyball? In addition to the body feels tired, the body of friends will all feel "sticky". This is due to the presence of dust and dirt that attaches to the skin, hair, clothing, and other surfaces that blend with the fat and oil in our bodies. Now the presence of dirt that fused together fat or oil can not be easily cleaned if only use water only, because water can not dissolve oil and fat. The solution is to use soap as a cleaning tool (household chemicals) that can remove fat or oily dirt

3. Detergent

Detergent is not the same as soap. The basic ingredients of the detergent are different from the basic ingredients of the soap. The basic ingredient of detergent is alkyl benzene sulfonate (ABS). This material is produced from petroleum processing. The washing power of the detergent is so strong when compared to soap and can also react to the water of the container. However, unlike soaps, detergents are difficult to break down by microorganisms, so that their use can pollute the environment. Foam from the unraveling detergent that can accumulate on the surface of the water, consequently blocking the diffusion of oxygen into the water. This can lead to the death of the ecosystem of life contained in water on which there is detergent foam

To overcome the environmental problems caused by detergent waste, currently alkyl benzene sulphonate (ABS) base material has been replaced with linear alkyl sulphonate. (LAS). Compared to (ABS), the use of LAS as a detergent base is more easily described by microorganisms and is known as an environmentally friendly material. The use of detergents already includes various purposes of use. Shampoo is a special detergent that is used as a hairdresser. Shampoo is made by using the same basic material, with the main material of abrasive material. While commonly used to wash kitchen equipment containing sodium tripolyphosphate, sodium metasilicate, and a little carbon.

4. Bleach

 Cloth bleaches are made to remove impurities on clothes that are difficult to clean. The usual bleach ingredients in daily life (household chemicals) contain 5.25% sodium perborate or sodium hypochlorite. This material can also serve as a germ killer (disinfectant). The use of excessive bleach can make the color of the clothes fade. For cleaning of toilets, bathroom tubs, ceramic flooring used cleaners containing nitric acid or sulfuric acid. Mixing between chemicals is very dangerous. If the bleach material contained in it sodium hypochlorite is mixed with a cleanser containing hydrochloric acid will produce chlorine gas. When inhaled in large quantities of this gas can cause damage to the throat also respiratory system, can even lead to death.

Prevention that can be done to avoid negative effects of bleach as follows:

a. Avoid the type of bleach that merkurinya there

b. Avoid Using bleach if stains or dirt are difficult to remove by detergent or soap

5. Fragrance

Initially, all fragrance ingredients are taken naturally from plants, for example: pandan leaves, cloves, jasmine, roses and others. However, at this time, fragrance deodorization can be made in the laboratory, although not as good as the original. Fragrance is used to give a delicious aroma. Smelly rooms can be sprayed with room deodorizer with a likable aroma. Fragrances are often added to other ingredients to make them more appealing, such as soaps and detergents. The perfume used directly on the body or clothing is called perfume. Typically, perfume contains 10% - 25% deodorizer which is dissolved in alcohol. Use of perfume together with other cosmetic ingredients can cause allergies.
