it is of which standard...??

Answer 2

Solution :
When a particular oxidation state becomes less stable relative to other oxidation states.
i.e one lower and other higher , it is said to undergo disproportion action .
For example , manganese (VI) becomes unstable relative to manganese (IV) in acidic solution .
3MnVIO2−4+4H+→2MnVIIO4+MnIVO2+2H2O
