Vedclass · Answer

(D) The total charge $(Q)$ supplied per minute is calculated as $Q = I 	imes t = 3.2 \ A 	imes 60 \ s = 192 \ C$.According to the reaction $Cu^{2+} + 2e^- ightarrow Cu$,the deposition of one $Cu^{2+}$ ion requires $2$ electrons.The total charge required for one mole of $Cu^{2+}$ ions is $2F$,but for a single ion,it is $2e$,where $e = 1.6 	imes 10^{-19} \ C$.The number of $Cu^{2+}$ ions deposited is given by $N = \frac{Q}{2e}$.$N = \frac{192}{2 	imes 1.6 	imes 10^{-19}} = \frac{192}{3.2 	imes 10^{-19}} = 60 	imes 10^{19} = 6 	imes 10^{20}$ ions.
