Problem

Zinc granules are added in excess to 500 mL of 1M

\text{Ni}(\text{NO}_3)_2

solution at

25^\circ\text{C}

until the equilibrium is reached. If

E_{\text{Zn}^{2+}/\text{Zn}}^\circ

and

E_{\text{Ni}^{2+}/\text{Ni}}^\circ

are -0.75 V and -0.24 V respectively, find out the

[\text{Ni}^{2+}]

at equilibrium. (IIT 1991)
