Question

14.A current of 0.2 A is passed in the aqueous solution of Cuso, for 1 hour. The mass of
cupper deposited at the cathode is
a. 0.235g
b. 0.118g
c. 0.635g
d. 0.0474g​

Answer 1

Answer:

Explanation:

equivalent of current = equivalent of copper deposited

0.2*3600 / 96500 = moles*2

moles=360/96500

moles = 0.00373

mass = 0.235 gm
