WebNov 12, 2015 · Explanation: Phosphoric acid, H 3P O4, is the parent acid. If it loses a proton, H +, we conserve both mass and charge, and H 2P O− 4 results. And what is the conjugate base of this beasty? Again, conserve mass and charge, and H P O2− 4 results. You did not conserve mass and charge in your question; I agree that this is all too easy to do.
