The metal that cannot be obtained by electrolysis of an aqueous solution of its salt is -

`Cr`

`Ag`

`Ca`

`Cu`

Text Solution

Verified by Experts

The correct Answer is:

The atom, present in upper portion of electrochemical series has very lower tendency to get reduced in free state from their stable oxidising state. Thus, it is too difficult to obtain Ca by electrolysis of its salts.
