Question

How many grams of cobalt metal will be deposited from a solution that contains Co²⁺ions if a current of 1.09 A is applied for 27.8 minutes.
grams

Answer 1

m=eq mt mass of the metal deposited et electro Chemical equivalent of the metal e- q is atomic weight Charge x 96500 colounds the amount of voltage q= ixt the current passed for a time t through the i is metal

m=eq. e for Caball- 58.933195 g/mol 2 x 96500 e = 0.00030535 334 m=eq q=ixt m= (0-00030535334) ( 1-094) (27.8 x60 sec) m= 0.5551699
