Chapter 50

What use(s) could be made of the flow of electrons in the wire?

Which is the stronger oxidizing agent, \(\mathrm{Cu}^{2+}(\mathrm{aq})\) or \(\mathrm{H}^{+}(\mathrm{aq})\) ?

The standard reduction potentials for \(\mathrm{Ag}^{+}(\mathrm{aq})\) and \(\mathrm{Au}^{+}(\mathrm{aq})\) are \(\begin{array}{lr} & E_{\mathrm{red}}^{\circ} \\ \mathrm{Ag}^{+}+1 \mathrm{e}^{-} \rightleftarrows \mathrm{Ag}(\mathrm{s}) & .80 \\\ \mathrm{Au}^{+}+1 \mathrm{e}^{-} \rightleftarrows \mathrm{Au}(\mathrm{s}) & 1.68\end{array}\) Which ion, \(\mathrm{Ag}^{+}(\mathrm{aq})\) or \(\mathrm{Au}^{+}(\mathrm{aq})\), exhibits the stronger pull on electrons?
