Question

the electrolyte used for the electroplating of silver on a brass spoon is Sodium argento cyanide solution​

Answer 1

Answer:

sodium argentocyanide

An aqueous solution of sodium argentocyanide is used for the electrolysis of silver as the migration of Ag+ ions is slow in this solution as compared to AgNO3 . Hence an even deposition of the silver metal is obtained on the article.

Explanation:

Sodium argentocyanide is a complex salt. Sodium silver cyanide is preferred to silver nitrate as an electrolyte for electroplating of an article with silver because the deposition of silver ion is slow and smooth and the coating is smooth.
