Question

In electroplating of copper by silver, the silver acts as an :

• A. anode
• B. cathode
• C. electrode
• D. electrolyte

Answer 1

The correct option is A anode

Silver plating on Steel spoon: A silver rod is made as anode and steel spoon as cathode. Potassiumargentocyanide $\left(K\right[Ag\left(CN{)}_2\right])$ is used as electrolyte.
$AgN{O}_3$ is not used as electrolyte because in that case the silver coating will be non-uniform as the electrolysis takes place rapidly.
In electroplating of copper by silver, silver rod is taken as anode.
