Answer» Orthophosphorus acid can be obtained by reacting `P_O_6" wIth "H_O` `O-underset(OH)underset(|)overset(OH)overset(|)(P)-OH+H" "O+underset(OH)underset(|)overset(OH)overset(|)(P)=O to O-underset(OH)underset(|)overset(OH)overset(|)(P)-O-underset(OH)underset(|)overset(OH)overset(|)(P)=O+H_(2)O` Although pyrophosphoric is tetrabais acid, yet only two sodium salts are known `Na_(2)P_(2)O_(7) and Na_2H_(2)P_(2)O_(7)`. `P_(4)O_(6)+6H_(2)O to 4H_(3)PO_(3) ` It structure is `O=underset(OH)underset(|)overset(H)overset(|)P-OH` Therefore, it is diabastic (b) `P_(4)O_(10)+6H_(2)O to 4 [O=underset(OH)underset(|)overset(OH)overset(|)P-OH]` This acid is tribasic. (d) `H_(3)PO_(4) overset(316^(@)C)to HPO_(3)+H_(2)O` The metaphosphate IONS up FORM `PO_(4)` units and are cyclic. The trimetaphosphate ion `(P_(3)O_(9)^(3-))` is shown below:
