chem320.cs.uwindsor.caTitration: Weak Acid with Strong Base We will consider the titration of 50.00 mL of 0.02000 M MES with 0.1000 M NaOH. MES is an abbreviation for 2-(N-morpholino)ethanesulfonic acid, which is a weak acid with pKa = 6.27. This the reverse of the Kb reaction for the base A−.Therefore, the equilibrium constant for is K = 1/Kb = 1/(Kw/Ka (for HA)) = 5.4 × 107.

Finally, you will use the pH meter in order to determine the effect of dissolved salts on the pH of water through the process of hydrolysis and the effect of adding an acid or base to a buffer.
Experiment 6 Titration II – Acid Dissociation Constant
chemistry.uccs.eduWhen a weak acid is titrated by a strong base, the fact that, in aqueous solution, the weak acid dissociates into a hydrogen ion and the conjugate base of the acid changes the appearance of the titration curve. The curve will look similar to Figure 3, which represents the titration of 0.1 M acetic acid with 0.1 M NaOH. NaOH titration of CH ...
