Calculate the pH of a 0.065 M formic acid (HCOOH)
solution.
Formic acid is a weak acid with Ka = 1.8 ×
10–4 at 25°C.
2.48 is WRONG answer!!!!!!
Write your answer to two decimal places. Calculate the pH of a 0.065 M formic acid (HCOOH) solution. Formic acid is a weak acid with 1.8x 10at 25°C. pH 2.48
