Question

Starting with sodium chloride how would you proceed to preparea. Sodium metalb. Sodium Hydroxidec. Sodium Peroxided. Sodium Carbonate

Answer 1

sodium metal can be obtained from sodium chloride NaCl by electrolysis
NaCl

Answer 2

Explanation:

Sodium metal - It is produced in Down's cell at 873 K by electrolysis of a fused blend of NaCl (40%) and CaCl2 (60%). Na, it is gathered released at the cathode, in kerosene oil While Cl2 develops at the anode.

Sodium hydroxide - It is produced using mercury cathode and carbon anode by electrolysis of an aqueous NaCl (brine) solutlon in Castner-Kellner cell. Sodium metal released at the cathode combines with mercury to form sodium amalgam, while at the anode Cl2 gas evolves.

Sodium peroxide - It is achieved in excess of air by heating sodium metal (which is acquired by molten NaCl's electrolysis). The sodium oxide that was initially created responds to Na2O2 with more O2.

Sodium carbonate - Using Solvay ammonia method, it is acquired. When CO2 passes through an ammonia-saturated focused brine solution (aqueous NaCl solution), NaHCO3 becomes precipitated. The subsequent heating of NaHCO3 provides Na2CO3.
