$\displaystyle 250$ mL of a waste solution obtained from the workshop of a goldsmith contains $\displaystyle 0.1 \mathrm{M} \mathrm{AgNO}_3$ and $\displaystyle 0.1$ M AuCl . The solution was electrolyzed at $\displaystyle 2$ V by passing a current of $\displaystyle 1$ A for $\displaystyle 15$ minutes. The metal/metals electrodeposited will be : $$\left(\mathrm{E}_{\mathrm{Ag}^{+} / \mathrm{Ag}}^0=0.80 \mathrm{~V}, \mathrm{E}_{\mathrm{Au}^{+} / \mathrm{Au}}^0=1.69 \mathrm{~V}\right) $$
