Concept explainers
(a)
Interpretation:
Among the pair
Concept introduction:
The oxidizing agent is a compound whose oxidation state falls during the course of the reaction and the reducing agent is the compound whose oxidation number increases. The compound having a greater tendency to be oxidized is the compound having the highest reducing power.
