An aqueous solution containing \( 1 \mathrm{M} \) each of \( \mathrm{Au}^{3+}, \mathrm{Cu}^{2+}, \mathrm{Ag}^{+}, \mathrm{Li}^{+} \)is being electrolysed by using inert electrodes. The value of standard reduction potentials are:
\( \mathrm{E}_{\mathrm{Ag}^{+} / \mathrm{Ag}}^{\mathrm{A}}=0.80 \mathrm{~V}, \mathrm{E}_{\mathrm{Cu}^{2+} / \mathrm{Cu}}^{\mathrm{o}}=0.34 \mathrm{~V} \), and
\(\mathrm{E}_{\mathrm{Au}^{3+} / \mathrm{Au}}^{0}=1.50 \mathrm{~V}, \mathrm{E}_{\mathrm{Li}^{+} / \mathrm{Li}}^{0}=-3.03 \mathrm{~V} \text {, }\)
With increasing voltage, the sequence of deposition of metals on the cathode will be:
