What is the sum of the oxidation state of phosphorus and number of P-OH bonds in H_3PO_4 ?

What are the oxidation states of phosphorus in the following compounds ? H_(3)PO_(2),H_(3)PO_(4),Mg_(2)P_(2)O_(7),PH_(3),HPO_(3)

What are the oxidation states of phosphorus in the following: (i) H_(3)PO_(3) , (ii) PCl_(3) , (iii) Ca_(3)P_(2) (iv) Na_(3)PO_(4) , (v) POF_(3)

A : PH_(5) is not possible . [R] : -5 oxidation state of phosphorus is not possible .

Phosphorus cannot form PH_(5) with its outer electronic configuration as 3s^(3)3p^(3) because (A)phosphorus cannot show +5 oxidation state (B)P H 5 is not a stable compound (C)Δ a H value of dihydrogen and Δ e g H value of hydrogen do not favour higher oxidation state of phosphorus (D)phosphorus is not very reactive hence does not form P H 5

The oxidation state of nitrogen varies from:

Phosphorus forms a number of oxoacids which differ in their structures and oxidation state of phosphorus. All the acids contain phosphorus atom//atoms linked tetrahedrally to four other atoms or groups. Each of them has at least one P=O or P rarr O unit and one P-OH unit. The OH group is ionisable but H atom linked directly to P is non-ionisabl. Structures of all the acids are considered to be derived either from phosphorus acid or phosphoric acid. Which one has + 3 oxidation state ?
