Q9 of 55 Page 1

A solution of is electrolysed between platinum electrodes using a current of 5.0 Ampere, for 20 minutes. What mass of Nickel will be deposited at the cathode?

(Given At mass of Ni = 58.7 g/mol, 1 F = 96500 C/mol)


Given,


T =


C = 5 A


Charge =


Q =


Q = 6000 C


According to the reaction,



Nickel deposited by 2 = 58.7


Thus, Ni deposited by 6000 C =


= 1.82 g


Therefore, 1.82 g of Ni will be deposited at the cathode.
