Chemistry - Electrochemistry Question with Solution | TestHub

According to the applications of electrochemical series on moving from top to bottom in electrochemical series, the values of $E_{\mathrm{oP}}^{\circ }$ of metals decrease, and thus reactivity of metals of $E_{\mathrm{op}}^{\circ }$ indicates greater reactivity of metal. On the other hand, ${\mathrm{F}}^{-}$is poor reductant while ${\mathrm{Cu}}^{2+}$ is strong oxidant. The metals placed above Mg in ECS decompose water at ordinary temperature to liberate ${\mathrm{H}}_2$. Oxides of Hg decomposes on heating.
