values of is −2.37 V, of is −0.76 V and is −0.44 V. Which of the following statements is CORRECT?

(A)Zn reduces Correct
(B)Zn reduces
(C)Mg oxidises Fe
(D)Zn oxidises Fe

Answer: (A)

Solution

Zn (−0.76 V) is a stronger reducing agent than Fe (−0.44 V), so \mathrm{Zn + Fe^{2+} \to Zn^{2+} + Fe} occurs; Zn cannot reduce
