In an electrochemical cell (Cu-Ag), why are solutions containing `Cu^(2+)` and `Ag^(+)` ions kept in separate containers ?

Text Solution

Verified by Experts

In case, the two salt solutions are kept in the same container, `Ag^(+)` ions will be reduced in the same container and no external current will be generated.
