The standard reduction potential values of some of the p-block ions are given below. Predict the one with the strongest oxidising capacity.
Solution
<p>Oxidizing capacity is an element's tendency to donate electrons, or the atmosphere's ability to oxidize compounds.</p>
<p>A higher standard reduction potential indicates a stronger oxidizing capacity. A substance with a higher standard reduction potential is move likely to gain electrons and act as an oxidizing agent in a redon reaction. The more positive the reduction potential, the stronger the oxidizing power of a species.</p>
<p>From the given options, the higher standard reduction potential is for lead $(\mathrm{Pb}) .(+1.67)$.</p>
<p>so, the p-block ion with strongest oxidizing capacity is Pb (lead).</p>
<p>Answer: Option 3) $E_{p_b{ }^{4+} / \mathrm{Pb}^{2+}}^0=+1.67 \mathrm{~V}$</p>
