What must be the concentration of

\text{Ag}^+

in an aqueous solution containing

\text{Cu}^{2+} = 1.0\,\text{M}

so that both the metals can be deposited on the cathode simultaneously. Given that

E^\circ_{\text{Cu}/\text{Cu}^{2+}} = -0.34\,\text{V}

and

E^\circ_{\text{Ag}^+/\text{Ag}} = 0.812\,\text{V}

T = 298\,\text{K}

(A) Nearly

10^{-19}\,\text{M}

(B)

10^{-12}\,\text{M}

(C)

10^{-8}\,\text{M}

(D) Nearly

10^{-16}\,\text{M}
