Phosphoric acid is a polyprotic acid, which makes it an ideal buffer. It gets harder and harder to separate the hydrogen from the phosphate, making the pK a values increase in basicity: 2.12, 7.21, and 12.67. The conjugate bases H 2 PO 4-, HPO 42-, and PO 43- can be mixed to form buffer solutions. Reaction.
