Question

During electroplating an article with silver, the electrolyte used is:

Answer 1

Correct option: $\left(C\right)$ Sodium argentocyanide solution.

• An aqueous solution of sodium argentocyanide $Na\left[Ag\right(CN{)}_2]$ is used for the electrolysis of silver as the migration of $A{g}^{+}$ ions is slow in this solution and hence uniform and smooth deposition takes place as compared to $AgN{O}_3$ solution.
