Q.
The standard reduction potential values of some of the $p$ -block ions are given below. Predict the one with the strongest oxidising capacity. [2025]

Solution

Q.
The standard reduction potential values of some of the $p$ -block ions are given below. Predict the one with the strongest oxidising capacity. [2025]

1 $E_{{Sn}^{4 +} / {Sn}^{2 +}}^{⊝} = + 1.15 V$

2 $E_{{Pb}^{4 +} / {Pb}^{2 +}}^{⊝} = + 1.67 V$

3 $E_{{Tl}^{3 +} / Tl}^{⊝} = + 1.26 V$

4 $E_{{Al}^{3 +} / Al}^{⊝} = - 1.66 V$

Ans.
(2)

Specie with highest reduction potential (i.e. highest willingness to get reduced) is strongest oxidizing agent.

Solution

Q. The standard reduction potential values of some of the p-block ions are given below. Predict the one with the strongest oxidising capacity. [2025]

1 ESn4+/Sn2+⊝=+1.15 V

2 EPb4+/Pb2+⊝=+1.67 V

3 ETl3+/Tl⊝=+1.26 V

4 EAl3+/Al⊝=-1.66 V

Ans. (2) Specie with highest reduction potential (i.e. highest willingness to get reduced) is strongest oxidizing agent.
