H-atom directly attached with 'P' atom is reducing in nature. H-atom attached with P atom through oxygen atom is acidic in nature.


Only orthophosphoric acid$\left({\mathrm{H}}_3\mathrm{P}{\mathrm{O}}_3\right)$has H-atom directly attached with 'P' atom, therefore, it is reducing in nature. Rest other are oxidising agents.
