Option C is not correct.
A 25.0 mL of a weak acid is titrated with a strong base (0.1 M). Calculate the pH of the solution during the titration if the weak acid concentration is 0.10 M and its Ka = 1.8 x 10-5 and 10.0 mL of base has been added. (Hint: use Henderson-Hasselbach equation). Question options: a) pH= 7.00 b) pH= 5.28 c) pH = 4.56 d) pH= 4.74
