phosphoric acid on heating to 525 and 875k yields meta phosphoric acid
Reaction: H3PO4———— HPO3+H2O (H3PO4 is a diprotic acid)
when we heat the phosphoric acid to 600 degrees we get phosphorus pentaoxide where condensation takes place along with dehydration,since the intermediate stage i.e meta phosphoric acid is a strong dehydrating agent.
Reaction: 2H3PO4————-P2O5+3H2O
