The standard reduction potential values of some of the p-block ions are given below. Predict the one with the strongest oxidising capacity.

Options

  1. A( E _ Pb ⁴⁺ / Pb ²⁺ ^ =+1.67 ~V )
  2. B( E _ Sn ⁴⁺ / Sn ²⁺ ^ =+1.15 ~V )
  3. C( E _ Al ³⁺ / Al ^ =-1.66 ~V )
  4. D( E _ Tl ³⁺ /Tl ^ =1.26 ~V )

Correct answer

A. ( E _ Pb ⁴⁺ / Pb ²⁺ ^ =+1.67 ~V )

Step-by-step solution

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