Which of the following is NOT a difficulty in setting SHE?
What mass of $$\mathrm{Mg}$$ is produced during electrolysis of molten $$\mathrm{MgCl}_2$$ by passing $$2 \mathrm{~amp}$$ current for 482.5 second?
(Molar mass $$\mathrm{Mg}=24 \mathrm{~g} \mathrm{~mol}^{-1}$$)
What is the conductivity of $$0.05 ~\mathrm{M} ~\mathrm{BaCl}_2$$ solution if its molar conductivity is $$220 ~\Omega^{-1} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$$ ?
A reaction, $$\mathrm{Ni}_{(\mathrm{s})}+\mathrm{Cu}_{(\mathrm{(M)})}^{+} \rightarrow \mathrm{Ni}_{(\mathrm{IM})}^{+}+\mathrm{Cu}_{(\mathrm{s})}$$ occurs in a cell. Calculate $$\mathrm{E}_{\text {cell }}^{\circ}$$ if $$\mathrm{E}_{\mathrm{Cu}}^{\circ}=0.337 \mathrm{~V}$$ and $$\mathrm{E}_{\mathrm{Ni}}^{\circ}=-0.257 \mathrm{~V}$$
