Question
A solution of silver nitrate is a good electrolyte but is not used for electroplating an article with silver.

Solution
A solution of silver nitrate is good electrolyte but is not used for electroplat ing an article with silver because, the deposition of silver will be very fast and hence not smooth and uniform.
