Question

Equivalent weight of ${CuSO_4}$ in terms of its molecular weight M in the following reaction is ${2 CuSO_4 + 4 KI -> Cu_2 I_2 + I_2 + 2 K_2SO_4}$

• A. M
• B. M/2
• C. M/4
• D. M/8

Answer 1

Answer: (A)

M

Answer 2

In the given reaction, ${Cu^{2+} -> Cu^{+}}$. Change in oxidation state = 1. Hence equivalent weight = Molecular weight.
