Dihydrogen phosphate ....
Amphiprotic == substance which can both donate and accept a proton. (A term used in the Bronsted-Lowry theory of acids and bases.)
H+ + H2PO4^-(aq) <==> H3PO4(aq) ..... accept a proton ... acts as BL base
H2PO4^-(aq) <==> H+ HPO4^2-(aq) ..... donate a proton ... acts as BL acid
Don't confuse amphiprotic with amphoteric. The latter refers to a substance which can behave as either an acid or a base depending on what it is reacting with.
All amphiprotic substances are amphoteric, but not all amphoteric substances are amphiprotic.
