Question

The cell reaction of a cell is Mg(s) + 2H+

(aq) tends to Mg2+ (aq) +H2(g) .If the standard reduction potential of Zn is -2.372 V, then the emf of the cell is
(A) +2.372 V (B)-2.372 V (C) 0.00V (D)-1.372 V​

Answer 1

Answer:

a) 2.372V

Explanation:

E=Ecathode-Eanode

=0-(-2.372)

=2.372
