The oxo-acids of `P_(2)O_(5)` are `H_(3)PO_(4), H_(3)P_(2)O_(7), HPO_(3)`, and `H_(3)PO_(3)`.

Text Solution

Verified by Experts

The oxo-acids are `H_(3)PO_(4),H_(4)P_(2)O_(7)` and `HPO_(3)` each has `P^(5+)` state.
`H_(3)PO_(3)` is not oxo-acid. `(P^(3+)` state).

  • Phosphorous forms two types of oxyacids, one having phosphorous in +1 or +3 oxidation state and other having phosporous in +1 or +3 oxidation state and other having phosphorous in +4 or +5 oxidation state. Phosphorous acids act as reducing agents as they tend to disproportionate. The important oxyacids of phosphorous are: H_(3)PO_(2),H_(3)PO_(3),H_(3)PO_(4),HPO_(3),H_(4)P_(2)O_(6),H_(4)P_(2)O_(7) . The number of OH group or groupds in oxoacids of phosphorous decides the basicity of the acid. H_(4)P_(2)O_(7) on heating at 600^(@)C gives
