Calculate the standard cell potential of the following cell at 25°C. Sn(s) | Sn2+(aq) || Cu2+(aq) | Cu(s).

Semmy [17]

Answer:

0.48 V

Explanation:

Usually in the cell notation, the left side shows oxidation. So,

Oxidation half reaction:

$Sn_{(s)}\rightarrow Sn^{2+}_{(aq)}+2e^-$ $E^o_{ox}=-E^o_{red}=-(-0.14\ V)=0.14\ V$

Reduction half reaction:

$Cu^{2+}_{(aq)}+2e^-\rightarrow Cu_{(s)}$ $E^o_{red}=0.34\ V$

$E^o_{cell}=E^o_{ox}+E^o_{red}= (0.14+0.34)\ V=0.48\ V$
