Question

(a) For the reduction of metal oxide, suggest a reducing agent other than carbon.
(b) Explain why, an aqueous solution of sodium chloride is not used for the electrolytic extraction of sodium metal.

Answer 1

Answer:

• Hydrogen.
• An aqueous solution of sodium chloride is not used for electrolysis because aqueous solution contains water as well which results in the formation of sodium hydroxide in the solution and sodium metal is not obtained. Hence molten sodium chloride is used to extract sodium from sodium chloride.

Answer 2

Explanation:

Answer:

Hydrogen.

An aqueous solution of sodium chloride is not used for electrolysis because aqueous solution contains water as well which results in the formation of sodium hydroxide in the solution and sodium metal is not obtained. Hence molten sodium chloride is used to extract sodium from sodium chloride.
