Question

Write the formulae of the oxoacids of phosphorus in which phosphorus is present in +5 oxidation state.

Answer 1

The oxoacids of phosphorus, where phosphorus is in +5 oxidation state, and their formulae are:

1. Orthophosphoric acid - H₃PO₄
2. Metaphosphoric acid - (HPO₃)_n
3. Pyrophosphoric acid (Diphosphoric acid) - H₄P₂O₇

These acids contain phosphorus in the +5 state with characteristic \[\ce{P = O}\] and \[\ce{P - OH}\] bonds and form condensed structures with \[\ce{P - O - P}\] linkages in some cases.
