Assertion (A) : Passage of 48,250C of electricity through cupric sulphate and ferrous sulphate solutions results in the deposition 0.5 moles each of iron and copper at the respective cathodes.
Reason (R): Number of equivalents of a metal deposited at cathode is equal to the number of faradays of electricity passed through the electrolyte.

Options

A. Both A and R are true and R is the correct explanation of A
B. Both A and R are true and R is not the correct explanation of A
C. A is correct and R is wrong
D. A is wrong and R is correct

Explanation

48,250 C is equal to 0.5 Faraday. Number of equal alents of metal deposited is equal to the number of faradays of electricity passed through the electrolyte and that means 0.5 equilvalents of copper and iron are deposited. Since they are bivalent ions, 0.5 equialents correspond to 0.25 moles
