A 50.00 mL sample of the weak acid CH3COOH (aq) at an initial concentration of 0.1000 M is titrated with a 0.1000 M solution of NaOH (aq) at 25°C. The Ka for CH3COOH is 1.8 x 10-5 at 25 °C. Calculate the pH of the solution after 20.00 ml of NaOH have been titrated. Calculate the pH at the half-equivalence point. What volume of NaOH must be added to reach the equivalence point? What is the pH at the equivalence point?
