Question

the condition which is most appropriate for electroplating with silver​

Answer 1

Answer:

Correct option is

C

sodium argentocyanide solution

Electroplating is the electrolytic process of deposition of a superior metal on the surface of a base metal or article.

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 AgNO

3

. Hence an even deposition of the silver metal is obtained on the article.

Explanation:

Another important use of electrolytic cells is in the electroplating of silver, gold, chromium and nickel. Electroplating produces a very thin coating of these expensive metals on the surfaces of cheaper metals, to give them the appearance and the chemical resistance of the expensive ones.

Answer 2

The condition which is most appropriate for electroplating with silver is sodium argentocyanide solution ( Ag NO$_{3}$)

As in the process of electroplating, a metal is coated by a thin layer of another metal by means of the electrolysis process in order to prevent corrosion of metal & increased its resistance.

Silver metal can only obtain by the process of electroplating of silver with an aqueous solution of sodium argentocyanide as the content of Ag+ ions is far low as compared to Ag NO$_{3}$ & Silver metal is obtained on the surface.
