Salt, which is one of the nutrient sources of all living things, including human, is also an important commercial substance.
Colorless salt (NaCl = sodium chloride), consisting of 40% sodium and 60% chlorine in pure form, with a specific gravity ranging from 2.1 to 2.35 g / cm3, melting point 800,8 ° C, boiling point 1412 ° C is a mineral.
Salt, which has been used as a nutrient since ancient times, is one of the most important inputs of chemical and other industries in our age. It is the general name given to the chemical compounds that are produced by the reaction of salts, acids and bases which are used in a broad sense in the language of chemistry. The salt consists of the plus-charged ion in the base and the minus-charged ion in the acid. The reaction between the acid and the base is the neutralization reaction, during which salt and water are formed. Most of the dissolved salt or solution salts decompose to minus plus positive charged ions and conduct electricity.
BASE + ACID → Salt + Water
Salts which are solid when separated from their solutions do not exhibit acid or base properties. Therefore, when dissolved in water, they do not change the pH of the water and the color of the litmus paper. Salts are more stable compounds than acids and bases and have higher melting and boiling points than the acids and bases that form them. Saline solutions have high physical buoyancy and bitter taste.
Sodium Chloride, commonly known as ra table salt,, is expressed by the NaCl symbol in the chemistry language. The salt which crystallizes according to the cubic system consists of Sodium (Na +) and Chlorine (Cl-) ions.
The color as produced from nature can be gray, yellow, red or even blue and green. The salt is colorless in pure form. Economical salt sources are divided into solid and liquid. The salt is present in liquid form in the seas, in salt water springs and in the form of solid rock salt.
