A polyprotic acid can donate more than one proton. A polyprotic base can accept more than one proton.

Poly means many. Polyprotic means lots of protons. Polyprotic acids can donate more than one protons and bases can accept more than one protons.

Polyprotic refers to many protons.
Bases accept protons, acids donate protons, so polyprotic acids donate many protons, while polyprotic bases accept more than one proton.

Polyprotic acids can donate more than one proton and polyprotic bases can accept more than one proton. For example, H2SO4 is a polyprotic acid and its conjugate base SO4^2- would be a polyprotic base.

A polyprotic acid can donate more than one proton, while a polyprotic base can accept more than one proton. Also, a good thing to know about polyprotic acids is that the acid becomes weaker after each proton it donates. For example, H2SO4 + H2O -> HSO4- + H3O+ and HSO4- + H2O -> SO4(-2) + H3O+
H2SO4 is a stronger acid than HSO4-
