A 45.3 mL sample of a 0.333 M aqueous hydrocyanic acid solution is titrated with a 0.250 M aqueous potassium hydroxide solution. What is the pH after 34.7 mL of base have been added? pH = What is the pH at the equivalence point in the titration of a 26.5 mL sample of a 0.322 M aqueous hydrocyanic acid solution with a 0.333 M aqueous potassium hydroxide solution? pH
