Answer 1

Heya❤❤❤



PREPARATION::

SODIUM CARBONATE-SOLVAY PROCESS. On industrial scale sodium carbonate is prepared by Ammonia Solvay Process. At first stage a saturated solution of sodium chloride is prepared which is also known "BRINE". Composition of solution of NaCl (brine) is 28% m/m.

USES::

☆It is often used in commercial detergent mixtures as well to treat hard water.

☆Sodium carbonate covers and kills mold spores.

☆In the manufacture of glass, it is combined with sand and calcium carbonate.

Answer 2

Sodium carbonate is obtained commercially through two different methods. The first method involves mining the mineral deposits of sodium carbonate, which is the main production method in the USA. In the second method, called the Solvay process, sodium chloride is reacted with ammonia to give sodium bicarbonate, which is then heated to give sodium carbonate.

The main uses of sodium carbonate are as water softener, food processing aid, pH modifier, swimming pool chemical and electrolyte. It is also used in the manufacture of glass, paper, soaps and detergents, and many other useful chemicals.
