MCQ

In an electrolysis experiment, a current $i$ passes through two different cells in series, one containing a solution of $CuSO _4$ and the other a solution of $AgNO _3$. The rate of increase of the weight of the cathodes in the two cells will be

A
In the ratio of the densities of $C u$ and $A g$
B
In the ratio of the at. weights of $C u$ and $A g$
✓
In the ratio of half the atomic weight of $C u$ to the atomic weight of $Ag$
D
In the ratio of half the atomic weight of $C u$ to half the atomic weight of $Ag$

✓

Answer

Correct option: C.

In the ratio of half the atomic weight of $C u$ to the atomic weight of $Ag$

(c) As $\frac{m_{C u}}{m_{A g}}=\frac{E_{C u}}{E_{A g}}=\frac{\left.\frac{1}{2} \text { (Atomic weight }\right)_{C u}}{\text { (Atomic weight })_{A g}}$
