H3PO4(aq) → H+(aq) + H2PO4-(aq)
H2PO4-(aq) → H+(aq) + HPO42-(aq)
HPO42-(aq) → H+(aq) + PO43-(aq)
Phosphoric acid, H3PO4(aq), is a triprotic acid. It helps in removing rust from iron, acidifying foods and beverages. It causes lowering of bone density.

Apologies for the incorrect response.
The correct expressions for the ionizations of phosphoric acid in aqueous solution are as follows:
H3PO4(aq) → H+(aq) + H2PO4-(aq)
H2PO4-(aq) → H+(aq) + HPO42-(aq)
HPO42-(aq) → H+(aq) + PO43-(aq)
The correct expressions for the ionizations of phosphoric acid in aqueous solution are as follows:
H3PO4(aq) → H+(aq) + H2PO4-(aq)
H2PO4-(aq) → H+(aq) + HPO42-(aq)
HPO42-(aq) → H+(aq) + PO43-(aq)
