Write the cell notation for an electrochemical cell consisting of an anode where \( \mathrm{Cr}^{2+}\left(\mathrm{aq}\right. \) ) is oxidized to \( \mathrm{Cr}^{3+}(\mathrm{aq}) \) at a platinum electrode and a cathode where \( \mathrm{Ni}^{2+}(\mathrm{aq}) \) is reduced to \( \mathrm{Ni}(\mathrm{s}) \). Assume all aqueous solutions have a concentration of \( 1 \mathrm{mol/L} \). \[ \mathrm{Cr}^{2+}(\mathrm{aq}) / \mathrm{Cr}^{3+}(\mathrm{aq}, 1 \mathrm{M}) \mathrm{Ni}^{2+}(\mathrm{aq}, 1 \mathrm{M}) \mathrm{Ni}(\mathrm{s}) \]
