Identify the conjugate base for each acid.

Question

Identify the conjugate base for each acid.

conjugate base of H3PO4:

conjugate base of H2PO−4:

Answer 1

Hello, the conjugate base of H3PO4 would be H2PO4- because of the loss of the H+ ion. You would lose one hydrogen ion, therefore will cause the base to have a -1 charge. The conjugate base of H2PO4- would be (HPO4)2- because of another loss of H+
