Polyprotic Acids and Bases

[Bailey Giovanoli 1L]

What I got from the lecture that included polyprotic acids and bases, essentially anything that has the potential to give or accept more than one H+. Obviously, there are likely more parameters to be met for this to actually be true, but this is the fundamental idea, correct?

[Chem_Mod]

Yes, that is correct. For instance, for H2SO4, since it has two protons, it has the potential to donate both of them, making it a polyprotic acid. Some other examples are H2CO3 and H3PO4, which also have multiple protons that it can potentially donate.

[FionaHunter21]

Yes, so the common ones have anions with a charge of -2 or more, such as sulfate and phosphate, and these can have either one, two, or sometimes three hydrogens.

yep polyprotic just means they can accept or donate more than 1 h+

[Andrew Yoon 3L]

Yeah so polyprotic acid and bases accept/donate more than 1 proton, in other words H+.
