Question

ln electroplating of silver, from where do ions come and where do they deposit?​

Answer 1

Answer: The silver anode bar gives up electrons to become silver ions  in this process. When the anode bar gradually dissolves to replenish the silver ions in the solution.

Since they are positively charged so they are attracted by negatively charged cathode, so the silver ions deposit on cathode in form of pure silver.

Hope it helps...

Answer 2

Explanation:

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.
