H_(3)PO_(3) is

H_(3)PO_(3) is

Statement-1 : Both H_(3)PO_(3) and H_(3)PO_(4) have the same number of hydrogen atoms but H_(3)PO_(4) is a tribasic acid and H_(3)PO_(3) is a dibasic acid. Statement-2 : 1 mol of H_(3)PO_(3) is neutralised by 2 mol of NaOH while 1 mol of H_(3)PO_(4) is neutralised by 3 mol of NaOH

Assertion : H_(3)PO_(4) is less acidic than H_(3)PO_(3) Reason : Oxidation state of phosphorus in H_(3)PO_(4) lt H_(3)PO_(3)

How is the reduction ability of H_(3)PO_(2) and H_(3)PO_(3) accounted on the basis of structures of molecules

Give reasons: H_(3)PO_(3) undergoes disproportionation reaction, but H_(3)PO_(4) does not.
