The standard reduction potential values of some of the p-block ions are given below. Predict the one with the strongest oxidising capacity.
  1. \(\mathrm{E}_{\mathrm{Pb}^{4+} / \mathrm{Pb}^{2+}}^{\ominus}=+1.67 \mathrm{~V}\)
  2. \(\mathrm{E}_{\mathrm{Sn}^{4+} / \mathrm{Sn}^{2+}}^{\ominus}=+1.15 \mathrm{~V}\)
  3. \(\mathrm{E}_{\mathrm{Al}^{3+} / \mathrm{Al}}^{\ominus}=-1.66 \mathrm{~V}\)
  4. \(E_{\mathrm{Tl}^{3+} / \mathrm{Tl}}^o=+1.26 \mathrm{~V}\)

Solution

The element having strongest oxidising capacity will have highest value of standard reduction potential
