What is normal hydrogen electrode? A galvanic cell consists of a metallic nickel plate immersed in 0.1M $\mathrm{Ni(NO_{3})_{2}}$ solution and a metallic plate of copper in 0.2M $\mathrm{CuSO_{4}}$ solution. Calculate the emf of this cell.

$E^\circ_{\mathrm{Ni^{2+}/Ni}} = -0.25\,\mathrm{V}$ $E^\circ_{\mathrm{Cu^{2+}/Cu}} = +0.34\,\mathrm{V}$
