Account for the following : H_3PO_2 and H_3PO_3 act as good reducing agents while H_3PO_4 does not. |
| Answer» Solution :Oxidation state of P in `H_3PO_2` is +1 , it can changeto higher oxidation STATES +3 and +5 . THEREFORE , it can act as REDUCING agent . Oxidation state of P in `H_3PO_3` is +3 , it can change to higher oxidation state +5 . Therefore , it can act as reducing agent . Oxidation state of P in `H_3PO_4` is +5 . Therefore , it can act as reducing agent. oxidation state of P in `H_3PO_4` is +5 . It is the highest . Therefore , it cannot act as a reducing agent. | |
