Q1

\( 250 \mathrm{~mL} \) of a waste solution obtained from the workshop of a goldsmith contains \( 0.1 \mathrm{~M} \mathrm{~AgNO}_{3} \) and \( 0.1 \mathrm{~M} \mathrm{~AuCl} \). The solution was electrolyzed at \( 2 \mathrm{~V} \) by passing a current of \( 1 \mathrm{~A} \) for 15 minutes. The metal/metals electrodeposited will be

\[ \left[\mathrm{E}_{\mathrm{Ag}^{*} / \mathrm{Ag}}^{0}=0.80 \mathrm{~V}, \mathrm{E}_{\mathrm{Au}^{*} / \mathrm{Au}}^{0}=1.69 \mathrm{~V}\right] \]
