Question

For electroplating of an object with silver, which of the following electrolytes is/are used?

• A. $AgN{O}_3$
• B. AgCN
• C. $CuS{O}_4$
• D. NaCl

Answer 1

The correct option is B

AgCN

First, the electrolyte must contain the ions of silver. So the electrolyte can be used is either AgCN or $AgN{O}_3$.

AgCN is more preferred than $AgN{O}_3$ because of using AgCN there will be better control of deposition of silver on the object.
