Question

Both H₂O and H₂PO₄- are amphoteric. Write an equation to show how each substance can act as an acid and another equation to show how each can act as a base.

Accepted Answer

H₂PO₄^-(aq) + H₂O(l) ⇋ H₃O⁺(aq) + HPO₄^2-(aq)

H₂PO₄^-(aq) + H₂O(l) ⇋ H₃PO₄(aq) + OH^-(aq)

Answer

H₂PO₄^-(aq) + H₂O(l) ⇋ H₃O⁺(aq) + HPO₄^2-(aq)

H₂PO₄^-(aq) + H₃O⁺(aq) ⇋ H₃PO₄(aq) + H₂O(l)

Answer

H₂PO₄^-(aq) + H₂O(l) ⇋ H₃O⁺(aq) + HPO₄^-(aq)

H₂PO₄^-(aq) + H₃O⁺(aq) ⇋ H₃PO₄(aq) + H₂O(l)

Answer

H₂PO₄^-(aq) + H₂O(l) ⇋ H₃O⁺(aq) + PO₄^2-(aq)

H₂PO₄^-(aq) + H₂O(l) ⇋ H₂PO₄⁺(aq) + OH^-(aq) + H₂(g)
