Chloroacetic acid, HC2H2ClO2,has a greater acid strength than acetic acid because theelectronegative chlorine atom pulls electrons away from the O-Hbond and thus weakens it. Calculate the hydronium ion concentrationand the pH of a 2.49E-3 M solution of chloroaceticacid. Ka is 1.3E-3.
[H3O+] = _____ M
pH = _____
