This question asks us to define what a polyprotic acid is.
00:05
Once we break down the word, it becomes pretty clear.
00:09
Poly is a prefix that means many or multiple.
00:14
Prodic is a term that refers to protons.
00:19
In the case of acid, we refer to hydrogens as our proton, because they have one proton in their composition.
00:29
However, because it's an acid, this proton does not have an electron, and therefore is positively charged.
00:40
So if we need to have a polyprotic acid, we need many or multiple h -plus atoms in our acid.
00:48
These h -pluses can be donated in acid -based chemistry.
00:54
Some examples of polyprotic acids can come from finding anions that have negatively charged, is equal to or greater than 2.
01:04
So, for example, we might have sulfate, which is s -o -4 -2 -minus.
01:14
We can also have sulfite, which is s -o -3, 2 -minus.
01:23
We can have phosphate, which is p -o -4, 3 -minus...
