write a short notes on the chemicals that is formed from common salt
Answers
Answer:
Answer. Common salt, or sodium chloride, is the chemical compound NaCl. Salt occurs naturally in many parts of the world as the mineral halite and as mixed evaporites in salt lakes. ... Underground salt deposits are what is found in both bedded sedimentary layers and domal deposits.

Answer:
The common salt is required in manufacture of sodium hydroxide, baking soda, washing soda, bleaching powder and many other chemicals.
When electricity is passed through an aqueous solution of sodium chloride (called brine), it decomposes to form sodium hydroxide. The process is called the chlor-alkali process. Chlorine gas is given off at the anode, and hydrogen gas at the cathode. Sodium hydroxide solution is formed near the cathode.
2NaCl(aq) + 2H2O(l) → 2NaOH(aq) + Cl2(g) + H2(g)
Bleaching powder is produced by the action of chlorine [Which is produced during the electrolysis of aqueous sodium chloride (brine).] on dry slaked lime [Ca(OH)2]. Bleaching powder is represented as CaOCl2
Ca(OH)2 + Cl2 → CaOCl2 + H2O
Baking soda which has chemical name as sodium hydrogencarbonate (NaHCO3) is produced using sodium chloride as one of the raw materials.
NaCl + H2O + CO2 + NH3 → NH4Cl + NaHCO3
Washing soda (Na2CO3.10H2O) is another chemical that can be obtained from sodium chloride. Sodium carbonate can be obtained by heating baking soda; recrystallisation of sodium carbonate gives washing soda.
