Question 376 of 380

Two voltameters one of copper and another of silver, are joined in parallel. When a total charge $q$ flows through the voltameters, equal amount of metals are deposited. If the electrochemical equivalents of copper and silver are $z_1$ and $z_2$ respectively the charge which flows through the silver voltameter is

Show answer and solution

Answer: (B) $\frac{q}{1+\frac{z_2}{z_1}}$

q_1 Z_1=q_2 Z_2

q=q_1+q_2

\therefore q_2=\frac{q}{1+\frac{Z_2}{Z_1}}
