When Phosphoric Acid behaves according to arrhenius theory in water, what are the two products formed by the first proton

dissociation?

Phosphoric acid is a triprotic acid. This means that it can dissociate in water up to three times, each time releasing a proton into the water as shown in the following reactions:

H3PO4 (s) + H2O (l) is in equilibrium with H3O + (aq) + H2PO4 - (aq)

H2PO4 - (aq) + H2O (l) is in equilibrium with H3O + (aq) + HPO42 - (aq)

HPO42 - (aq) + H2O (l) is in equilibrium with H3O + (aq) + PO43 - (aq)

Explanation:

Phosphoric acid having contact with water, dissociating from a proton up to three times, that is why the three possible reactions are determined above.

This acid is an acid that belongs to oxo acids and its formula is H3PO4
