Key Terms to Review (33) Acidic Solution: An acidic solution is a water-based liquid that has a pH level less than 7. It's characterized by an excess of hydrogen ions (H+).The buffer "works" because the HCl reacts with the base component of the buffer (A−) according to the equation below. HCl + A− → HA + Cl−. Thus the buffer solution eliminates all of the HCl (or the H+ or H3O+) and sacrifices some of the weak base (A−) making more weak acid, HA.AP Chemistry test data overlooks factors like the quality of teachers and schools.
