Vedclass · Answer

(C) According to Faraday's second law of electrolysis,when the same quantity of electricity is passed through different electrolytes connected in series,the masses of the substances deposited are proportional to their chemical equivalents.$\frac{m_{Ag}}{m_{Cu}} = \frac{E_{Ag}}{E_{Cu}}$Given: $m_{Cu} = 1.6 \ g$,$E_{Cu} = 32$,$E_{Ag} = 108$.Substituting the values:$m_{Ag} = \frac{108}{32} 	imes 1.6$$m_{Ag} = 3.375 	imes 1.6 = 5.4 \ g$Therefore,the mass of silver deposited is $5.4 \ g$.

The chemical equivalents of copper and silver are $32$ and $108$ respectively. When copper and silver voltameters are connected in series and electric current is passed through for some time,$1.6 \ g$ of copper is deposited. Then,the mass of silver deposited will be .......... $g$.
