Question
Which among the following is the strongest oxidizing agent and why?? IO4- BrO4- ClO4-
Joshi sir comment
Inertness of BrO4- at room temperature stands in sharp contrast to its high thermodynamic oxidizing power, which is greater than that of any other oxohalogen ion that persists in aqueous solution. The oxidation potential is
BrO4-+ 2H+ + 2e- -------> BrO3- + H2O E = +1.853 V
(1.201 V for ClO4- and 1.653 V for IO4-)
