20.6 mL sample of a 0.441 M
aqueous hypochlorous acid solution with a
0.344 M aqueous sodium hydroxide
solution?
pH =_______
2) When a 28.7 mL sample of a 0.348 M aqueous hydrofluoric acid solution is titrated with a 0.307 M aqueous potassium hydroxide solution, what is the pH at the midpoint in the titration?
pH=________
3)
A 19.7 mL sample of a 0.385 M
aqueous hydrocyanic acid solution is titrated with
a 0.391 M aqueous sodium
hydroxide solution. What is the pH at the start of the
titration, before any sodium hydroxide has been
added?
pH =
