Question

The electrolytes usually used in the electroplating of gold and silver, respectively, are
(A) [Au (CN2)] and [AgCl2]
(B) [Au(NH3)2) and (Ag(CN),
(C) [Au(CN)2] and [Ag(CN)2]
(D) [Au(OH)] and [Ag(OH)2]​

Answer 1

Option ( C ) [ [Au(CN)2] and [Ag(CN)2]

The Anode is a bar of silver metal, and the electrolyte (the liquid in between the electrodes) is a solution of Silver cyanide, [Ag(CN) 2 ] −

, in water.

Gold plating is done in much the same way, using a gold anode and an electrolyte containing Gold cyanide, [Au(CN) 2] − .

Option C is correct

Answer 2

Explanation:

The electrolytes usually used in the electroplating of gold and silver, respectively, are

The electrolytes usually used in the electroplating of gold and silver, respectively, are(A) [Au (CN2)] and [AgCl2]
