Chloroacetic acid, HC2H2ClO2, has a greater acid strength than acetic acid, because the electronegative chlorine atom pulls electrons away from the O-H bond and thus weakens it. Calculate the hydronium-ion concentration and the pH of a 0.0059 M solution of chloroacetic acid. Ka is 1.3 10-3.
what is the hydronium-ion concentration __M and the pH___?
