Content

Getting

Potassium Bromate Electrolysis :

{\mathsf {KBrO_{3}+H_{2}O\ {\xrightarrow {e^{-}}}\ KBrO_{4}+H_{2}}}

{\ displaystyle {\ mathsf {KBrO_ {3} + H_ {2} O \ {\ xrightarrow {e ^ {-}} \ KBrO_ {4} + H_ {2}}}}

Physical Properties

Potassium perbromate forms colorless crystals, moderately soluble in water without hydrolysis . The solution has a neutral reaction.

Chemical Properties

Decomposes when heated:

{\mathsf {2KBrO_{4}\ {\xrightarrow {275^{o}C}}\ 2KBrO_{3}+O_{2}}}

{\ displaystyle {\ mathsf {2KBrO_ {4} \ {\ xrightarrow {275 ^ {o} C}} \ 2KBrO_ {3} + O_ {2}}}}

{\mathsf {KBrO_{4}\ {\xrightarrow {>390^{o}C}}\ KBr+2O_{2}}}

{\ displaystyle {\ mathsf {KBrO_ {4} \ {\ xrightarrow {> 390 ^ {o} C}} \ KBr + 2O_ {2}}}

It is a strong oxidizing agent:

{\mathsf {2KBrO_{4}+I_{2}\ {\xrightarrow {}}\ 2KIO_{4}+Br_{2}}}

{\ displaystyle {\ mathsf {2KBrO_ {4} + I_ {2} \ {\ xrightarrow {}} \ 2KIO_ {4} + Br_ {2}}}
