25.00 mL of a solution of a weak monoprotic acid, HX, was titrated with a 0.0640 M solution of NaOH, requiring 18.22 mL to neutralize the acid. If the Ka for the acid is 3.60*10-6, what is the pH at the equivalence point of this titration? You may assume that the temperature is 25 °C. 5.06 7.00 8.56 5.44 8.94
