Conjugate base hpo4 2. Phosphoric acid is the parent acid, i.e. H 3P O4. Remove a proton from this, we get, H 2P O− 4 as the conjugate base. Or rather phosphoric acid donates a proton to water to give H 3O+ and H 2P O− 4. And remove a proton from H 2P O− 4 to get H P O2− 4 as the conjugate base. In water that's about as far as you go.
