A 35.0-mL sample of 0.20 M LiOH is titrated with 0.25 M HCl. What is the pH of the solution after 23.0 mL of HCl have been added to the base?

Calculate the pH of a 0.021 M NaCN solution. [Ka(HCN) = 4.9 × 10–10]

If the pH of a buffer solution is greater than the pKa value of the buffer acid, the buffer will have more capacity to neutralize added base than added acid.

Which best describes the pH at the equivalence point of a titration of a weak acid with a strong base?

Which of the following is correct for the equivalence point in an acid-base titration?

Hydroxylamine, HONH2, readily forms salts such as hydroxylamine hydrochloride that are used as antioxidants in soaps. Hydroxylamine has Kb = 9.1 × 10–9. What is the pH of a 0.025 M HONH2 solution?
