Question

How many grams of cobalt metal will be deposited from a solution that contains Co²⁺ions if a current of 0.883 A is applied for 37.8 minutes.
grams

Answer 1

nF 3 I from Faraday's first law of electrolysis - The mass of any substance deposited at any electrode during et electrolysis is directly propotions to the quantity of electricity passed through the solution. I was W X It [:$= It] w = M. It - where w= Mass of electrolyte. M = Molecular weight of electrolyte I= o Current time n= charge of electrolyte. F = Faraday coustant 596500 Columb Imal- Here M= 59 gol mol, I = 0.883 A maz a 4 = 37.8 min = 37.8 x 6o see = 2268 sec w 59 X ,883 x 0 2268 - 2x 96500 =0.61 gm 10. 61 gom Cobalt metal will deposited] H +
