Question

Common name of sodium chloride is ……….salt.

Answer 1

Hint: Sodium chloride is the salt responsible for the salinity of seawater. Salinity is defined as the amount of the salt that is present in water.

Complete answer:
Sodium chloride is an ionic compound with chemical formula NaCl representing a 1:1 molar ratio of sodium and chloride ions. It is commonly used as a food preservative. Large quantities of sodium chloride are used in many industrial processes and it is a major source of sodium and chlorine compounds. A second major application of sodium chloride is de-icing of roadways in sub-freezing weather. Common name of sodium chloride is table salt as we use it on a daily basis in the preparation of food items.
Sodium chloride is a white crystalline powder, odorless and has strong saline taste. Sodium chloride is readily soluble in water and insoluble or only slightly soluble in other liquids. When it is melted or dissolved in water, the ions can move about freely, so that dissolved or molten sodium chloride is a conductor of electricity. It can be decomposed into sodium and chlorine by passing an electrical current through it.
The decomposition of sodium chloride is given below:
$NaCl\xrightarrow{{electricity}}N{a^ + } + C{l^ - }$

Thus the common name of sodium chloride is Table salt.

Note: NaCl can be made naturally by the help of mining or it can be obtained from the ocean. Rock salt and brine are the two sources of the salt. Remember that sodium chloride is used in the food industries as the taste enhancer, in the glass manufacturing industry, etc.
