In phosphoric acid, why is it relatively easy to remove the first proton, considerably harder to remove the second proton, and extremely difficult to remove the third proton in chemical reactions?

I'm not sure about this one is it because each time a proton is removed, more negative charge is built up and the molecule is attracted more to the remaining protons, thus making them less acidic?

That's a great answer.
