a) A buffer solution contains 0.455 M NaHSO3 and 0.254 M K2SO3. Determine the pH change when 0.096 mol NaOH is added to 1.00 L of the buffer.
pH after addition â pH before addition = pH change = ___________
b) Determine the pH change when 0.131 mol KOH is added to 1.00 L of a buffer solution that is 0.460 M in CH3COOH and 0.280 M in CH3COO-.
pH after addition â pH before addition = pH change = ___________
c) When a 25.0 mL sample of a 0.369 M aqueous acetic acid solution is titrated with a 0.311 M aqueous sodium hydroxide solution, what is the pH at the midpoint in the titration?
pH = _________
d) A 17.3 mL sample of a 0.427 M aqueous hypochlorous acid solution is titrated with a 0.441 M aqueous potassium hydroxide solution. What is the pH at the start of the titration, before any potassium hydroxide has been added?
pH = __________
