(a) In the button cell, widely used in watches and other devices, the following reaction takes nlace:
\[
\mathrm{Zn}(\mathrm{s})+\mathrm{Ag}_{2} \mathrm{O}(\mathrm{s})+\mathrm{H}_{2} \mathrm{O}(l) \rightarrow \mathrm{Zn}^{2+}(\mathrm{aq})+2 \mathrm{Ag}(\mathrm{s})+2 \mathrm{OH}^{-}(\mathrm{aq})
\]
\( P \)
Determine \( \mathrm{E}^{0} \) and \( \Delta_{\mathrm{r}} \mathrm{G}^{0} \) for the reaction
Given : \( \mathrm{E}_{\mathrm{Ag}^{+} / \mathrm{Ag}}^{\circ}=+0.80 \mathrm{~V}, \mathrm{E}_{\mathrm{Zn}^{+2} / \mathrm{Zn}}^{\circ}=-0.76 \mathrm{~V} \)
W.
(b) Explain with examples the terms weak and strong electrolytes. How can these be distinguished.
