The $emf$ of a galvanic cell,with electrode potentials of silver $= +0.80 \ V$ and that of copper $= +0.34 \ V$,is ........... $V$.

If the reduction potential is more,then

If $E^0_{Fe^{2+} / Fe} = -0.441 \ V$ and $E^0_{Fe^{3+} / Fe^{2+}} = 0.771 \ V$,the standard emf of the cell reaction $Fe_{(s)} + 2 Fe^{3+}_{(aq)} \longrightarrow 3 Fe^{2+}_{(aq)}$ is

If more than one species is available near the cathode,which species will undergo a reduction reaction? Provide suitable examples.

The standard hydrogen electrode has a zero electrode potential because .....

Given,the standard potentials $E_{(Cu^{2+}/Cu)}^{\circ}$ and $E_{(Cu^{+}/Cu)}^{\circ}$ as $0.340 \ V$ and $0.522 \ V$ respectively,the value of $E_{(Cu^{2+}/Cu^{+})}^{\circ}$ is $.... \ V$
