a) Trichloroacetic acid, CCl3COOH, has an acid dissociation constant of 2.0 à 10-1 at 25 °C. Calculate the pH of a 0.0420 M trichloroacetic acid solution. (The correct answer is 1.45 but I would like to see the work)
ph = ______
b) Trichloroacetic acid, CCl3COOH, has an acid dissociation constant of 2.0 à 10-1 at 25 °C. How many times greater is the H3O+concentration in this solution than in a 0.0420 M acetic acid (Ka = 1.8Ã10-5)? (The correct answer is 41 but I would like to see the work)
