Vedclass · Answer

(C) According to Faraday's second law of electrolysis,the mass of substances deposited is proportional to their equivalent weights when the same quantity of electricity is passed through them.Equivalent weight of $Ag = \frac{108}{1} = 108$.Equivalent weight of $Cu = \frac{64}{2} = 32$.Using the formula: $\frac{	ext{Mass of } Cu}{	ext{Mass of } Ag} = \frac{	ext{Equivalent weight of } Cu}{	ext{Equivalent weight of } Ag}$.$	ext{Mass of } Cu = \frac{32}{108} 	imes 10.8 \ g = 3.2 \ g$.

The atomic weights of silver and copper are $108$ and $64$ respectively. $A$ silver voltameter and a copper voltameter are connected in series,and when current is passed,$10.8 \ g$ of silver is deposited. The mass of copper deposited will be ............. $g$.
