State titrant are required to reach the equivalence point

Reference no: EM13166043

A 35.00-mL solution of 0.2500 M HF is titrated with a standardized 0.1991 M soluton of NaOH at 25 C. The pH of the HF solution before titrant is added is 1.88 and 43.948 mL of titrant are required to reach the equivalence point.
(a) What is the pH at 0.50 mL before the equivalence point?
(b) What is the pH at the equivalence point?
(c) What is the pH at 0.50 mL after the equivalence point?
