Question

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

Options:

Answer:

B

Solution:

$q_{1} Z_{1} = q_{2} Z_{2}$ $q = q_{1} + q_{2}$ $∴ q_{2} = \frac{q}{1 + \frac{Z _{2}}{Z _{1}}}$

q 1 ​ Z 1 ​ = q 2 ​ Z 2 ​ q = q 1 ​ + q 2 ​ ∴ q 2 ​ = 1 + Z 1 ​ Z 2 ​ ​ q ​
