CBSE Class 12-science Answered
100 ml of a neutral solution containing 0.2 g of copper was electrolysed till the whole of copper was deposited. The current strength was maintained at 1.2 amperes and the volume of solution was maintained at 100ml. Assuming 100% efficiency, find out the time taken for deposition of copper. [Atomic weight of copper = 63.58]

Expert Answer
W = 0.2; I = 1.2 amperes
Z for Cu = 
We know that W = Z × I × t
t = 
Substituting the values in the above equation, t =
