Problem

The standard reduction potential of

E^\circ_{\text{Bi}^{3+}/\text{Bi}}

and

E^\circ_{\text{Cu}^{2+}/\text{Cu}}

are

0.226\text{ V}

and

0.344\text{ V}

respectively. A mixture of salts of

\text{Bi}^{3+}

and

\text{Cu}^{2+}

at unit concentration each is electrolysed at

25^\circ\text{C}

. To what value can

[\text{Cu}^{2+}]

be brought down before bismuth starts to deposit during electrolysis?
