The chemical equivalent of copper and zinc are 32 and 108 respectively. When copper and silver voltameter are connected in series and electric current is passed through for sometimes, 1.6 g of copper is deposited. Then, the mass of silver deposited will be
Correct option is C. 5.4 g
From Faraday’s law, m/E = constant
where m = mass of substance deposited, E =chemical equivalent. $$ \therefore \dfrac{m_{2}}{m_{1}} = \dfrac{E_{2}}{E_{1}} \Rightarrow m_{2} = \dfrac{108}{32} \times 1.6 = 5.4g $$
