Some important compounds of sodium, notes

The most important compounds of sodium that are of commercial importance are as follows-

Sodium Carbonate

• It is commonly known as Washing Soda with molecular formula Na2CO3.10H2O.
• It is synthesized by Solvay process. During this process, sodium carbonate is synthesized using sodium chloride and calcium carbonate. Sodium Chloride (NaCl)

• The main source of sodium chloride is sea water.

• Evaporation of sea water is the most common method to obtain sodium chloride.

• Crude sodium chloride is obtained by crystallization of brine solution, containing sodium sulphate, calcium sulphate, calcium chloride and magnesium chloride

  Sodium Hydroxide (NaOH)

• Also known as Caustic Soda.

• The process of formation of sodium hydroxide is known as Castner-Kellner Cell. 

Sodium Hydrogen Carbonate

• It is also known as Baking Soda with a molecular formula, NaHCO3.

• Its decomposition forms carbon-dioxide.
