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. Which is harder chemistry or physics?
