Question

The EMF of the cell Ni | Ni2+ || Cu2+ | Cu(s) is 0.59 volt. The standard reduction electrode potential of copper electrode is 0.34 volt. The standard reduction electrode potential of nickel electrode will be (A) 0.25 volt (B) -0.25 volt (C) -0.50 volt (D) -0.025 volt

Tardigrade Admin · Accepted Answer

-x = 0.59 x = 0.34 -0 .59 = -0 .25 V

Q. The EMF of the cell $N i ∣ N i^{2 +} ∣∣ C u^{2 +} ∣ C u (s)$ is 0.59 volt. The standard reduction electrode potential of copper electrode is 0.34 volt. The standard reduction electrode potential of nickel electrode will be

$0.25$ volt

$- 0.25$ volt

$- 0.50$ volt

$- 0.025$ volt

$- x = 0.59$
$x = 0.34 - 0.59 = - 0.25 V$
