Answer:
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
