Standard reduction potential (in volts) of the perhalate ions are gives as below‐
${\text{ClO}}_{\text{4}}^{-}\text{+}{\text{2H}}^{\text{+}}\text{+}{\text{2e}}^{-}\to {\text{ClO}}_3^{-}\text{+}{\text{H}}_{\text{2}}\text{O;}{\text{E}}^{\text{o}}\text{=}\text{1}\text{.19}\text{V}$
${\text{BrO}}_{\text{4}}^{-}\text{+}{\text{2H}}^{\text{+}}\text{+}{\text{2e}}^{-}\to {\text{BrO}}_3^{-}\text{+}{\text{H}}_{\text{2}}\text{O;}{\text{E}}^{\text{o}}\text{=}\text{1}\text{.74}\text{V}$
${\text{IO}}_{\text{4}}^{-}\text{+}{\text{2H}}^{\text{+}}\text{+}{\text{2e}}^{-}\to {\text{IO}}_3^{-}\text{+}{\text{H}}_{\text{2}}{\text{O; E}}^{\text{o}}\text{=}\text{+1}\text{.65}\text{V}$
More the standard reduction potential, more is the tendency of perhalite ion to undergo reduction and stronger will be an oxidizing agent.
