The standard reduction potential values of some of the p-block ions are given below. Predict the one with the strongest oxidising capacity.
(a) V
(b) V
(c) V
(d) V
- a
- b
- c
- d✓
Strategy: Oxidizing capacity relates to the tendency of a species to gain electrons (be redu\ced). The species with the highest (most positive) standard reduction potential () is the strongest oxidizing agent.
Comparison:
- (a)
- (b)
- (c)
- (d) (Highest)
Conclusion: Lead(IV) is highly unstable and will strongly tend to redu\ce to Lead(II), especially due to the inert pair effect.
