Deionized water is also spelt deionized water or call. Another name that sounds a bit more understandable to many people is demineralized water. However, it is called or spelled, it means water which is extremely little ions or minerals in it. The ions are charged atoms. Atoms become charged after gain or lose at least one electron. A sodium atom (Na) becomes a sodium ion after losing an electron (Na +). An atom of chlorine (Cl) becomes a chloride ion (CL?) after gaining an electron. Metallic salts are composed of ions and molecules do not. That's why they're called Ionic compounds. The example was just as popular. Table salt is sodium chloride (NaCl) and is a popular household Ionic substance. For those who have forgotten the basic chemistry, NaCl is not composed of molecules of NaCl, but is actually composed of ions Na + and Cl-bound tightly together by electrostatic forces. However, water does the trick to separate ions. As table salt dissolves in water dissociates to its component ions. The same thing happens at any other salts in water and why water is a solvent, it is never found in pure form, but he always impurities. Filtration and chlorination of water can remove organic impurities and bacteria, but minerals may still be present. These minerals are present in the form of ions such as calcium (Ca ++) and magnesium (Mg ++), as well as chlorides, nitrates, and carbonates. If the water contains minerals and ions cannot be a health problem, has some drawbacks. For example, tap water, which has a lot of impurity ions leave blemishes or stains on the surfaces when used as a cleaning agent. This is where deionization steps.
Deionization is the process of removal of ionic impurities in the water. It is also called demineralization. In the industrial scene, this may involve two phases. The first phase removes positive ions of sodium, potassium, calcium, magnesium and iron. They are displaced by hydrogen ions (H +). The second step removes negative ions such as chloride, nitrate and sodium bicarbonate. These are then moved from hydroxyl ions (OH-). The resulting water teems with hydrogen and hydroxyl ions, which fuse to form water molecule. Both stages use resin beads that serve as an ion-exchange site.
The resulting water is said to have no value of pH since there are no ions to measure the pH. However, water is stripped of its solvent ion is a more aggressive. If left in an open container, which sucks the carbon dioxide from the air. The result of an acidic solution, causing the water to take a lower pH value. However, the solution to the boiling point of heating can remove carbon dioxide and restore the quality of deionized water.
There are controversies about the effects of demineralized water to drinking. There is a fear that because it is too pure may actually be harmful to humans. Water extremely pure steal the body out of its electrolyte ions or useful. The issue with this statement is based on very little evidence.
Industrial purposes never deionized water can be rebutted. It supports extensive application in semiconductor industry, as it uses during processing and cleaning of materials as silicon wafer. The optical industry also relies on this type of high purity water, since the optical surfaces are supposed to be extremely clean as requirement for the coating. GLASSWARES laboratory are rinsed in water as tap water is never recommended for this purpose. Water that is free of ions is also used in car wash shops. It is also very suitable and is used in the cleanup. The effectiveness of this pure water as a cleaning agent due to its aggressiveness as a solvent, since water that does not contain dissolved ions will tend to draw solutes by ions or surrounding surfaces. This means that no spots or stains left on surfaces.
In addition, in the manufacture of pharmaceutical products and cosmetics, water is often used because it does not contain impurities that can cause adverse reactions with other substances used in these products.
