I know that it is mainly used to describe acids, but apart from that, I am not really sure what it means.
mono = one?

Re: Definition of Monoprotic
monoprotic just means the acid has one donatable proton, for example HNO3. Whereas polyprotic would have more than 1 proton like H2SO4.
Re: Definition of Monoprotic
Yep. If an acid is a monoprotic acid, then it is only able to offer one hydrogen ion to a solution.

Re: Definition of Monoprotic
Since the hydrogen atom has only one proton and one electron, when the electron is removed from the atom, the atom exists as a solitary proton. Thus H+ atoms are simply free protons. When the H+ is able to bond to form a larger molecule, the molecule has one or more protons bonded to it. Ergo a molecule, or more specifically, an acid that has only one H+ bonded to it is monoprotic. This means that acids like HNO3 and HCl are monoprotic. However, it is worth mentioning that monoprotic only refers to the number of hydrogen atoms that can be ionized; for example, CH3COOH has four hydrogen atoms within the molecule, but the hydrogen atoms within the acetate anion (CH3COO) cannot be ionized, so CH3COOH is monoprotic.

Re: Definition of Monoprotic
I would agree with the others, monoprotic just means the acid has one donatable proton to give off whereas polyprotic acids can give off multiple.
