You'll get a detailed solution from a subject matter expert that helps you learn core concepts. ...H2po4 (dihydrogen phosphate) is the conjugate acid of the hydrogen phosphate ion (hpo4^2-). In an acid-base equilibrium, when hpo4^2- accepts a proton (H+), it forms …The resulting base is called the conjugate base. The same is true for bases-- when in equilibrium, it will accept a proton, and become a conjugate acid. Here are the equilibrium expressions: HPO 4 2-+ H 2 O …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.

Hence, in order to get the conjugate base of a species, we should consider that substance as an acid and vice versa. For example, H 2SO 4→HSO 4−+H +. Therefore, conjugate base of H 2SO 4 is HSO 4−. Using this logic, for the given example: H 2PO 4−→HPO 4−2+H +. Hence, conjugate base of H 2PO 4− is HPO 4−2. Option A is correct.mL of 0.030 M KH2PO4 with 100. mL of 0.050 M K2HPO4.
