It's important to know that polyprotic acids and bases have the ability to accept/donate more than one hydrogen ion. These polyprotic acids and bases have the ability to have a much stronger effect on the resulting solution pH, as they can greatly influence the hydrogen ion concentration within a particular solution.

I think it's important to add that they are able to release or take up multiple H+ because of the stability of their anion compounds.

A lot of these polyprotic substances are things that have an ion in them that he went over in class when discussing Lewis structures. It’s important to note that these ions are stabilized with resonance so they are good acids

One example of the significance of polyprotic acids and bases is how the oceans help maintain a constant concentration of carbon dioxide in the atmosphere. Because carbonic is a polyprotic acid, it can successively donate protons, so when it reacts with water, it donates H+ to water reducing acidity.

Just know that they donate more than one hydrogen

Polyprotic means there are multiple acidic protons that dissociate. Polyprotic acids can lose 2 or more of these protons, which become less acidic as they are lost in sequential steps.
