A weak diprotic acid, H₂A ionizes progressively based on the following equilibrium: H₂A HA¹. A-² One mole of the acid in aqueous solution is titrated progressively with a standard solution of a strong base [-OH]. The change in pH as the base is added is monitored using a pH meter and the pH is noted. The data gathered is used to construct the following titration curve. 14 13 12 11 10 Hd 876543210 0 0.2 0.4 0.6 0.8 1 1.2 1.4 1.6 1.8 2 2.2 2.4 2.6 2.8 moles [ -OH] added
