A 100 watt, 110 volt incandescent lamp is connected in series with an electrolytic cell containing CdSO4 solution. What weight of Cd will be deposited by current flowing for 10 hr.? At.wt. of Cd = 112.4

Text Solution

Verified by Experts

100 W lamp will produce `100 J s^(-) implies 100 J =100xxC implies C=10/11 `Coulumbs Therefore,total coulumb passed in `10 h =10/11xx10xx60xx60=32727.27 C`
Number of gram equivalent of `Cd^(2+)` deposited `=32727.27/96500=0.34`
Weight of Cd deposited `=0.34xx112.4/2 g=19.1 g`
