How much time would it take in minutes to deposit 1.18 g of metallic copper on a metal object when a current of 2.0 A is passed through the electrolytic cell containing Cu^(2+) ions? [Molar mass of Cu = 63.5 g mol^(-1), 1F = 96,500 Cmol^(-1)] |

Answer» SOLUTION :`m = Z xx I xx t` `1.18 = (63.5)/(2 xx 96500) xx 2 xx t` `t = (1.18 xx 2 xx96500)/(2 xx 63.5)` `= 1793.23` SEC `= (1793.23)/(60) = 29.88` min. |
