Phenol, C6H5OH, is a weak organic acid: C6H5OH(aq) = С6H5O¯(aq) + H+ (aq) Although somewhat toxic to humans, it is widely used as a disinfectant and in the manufacture of plastics. What is the equilibrium hydrogen ion concentration in a 0.16M acid solution? What is the pH of the solution? Ka of C6H5OH = 1.3 x 10-10 Kc 1.3 x 10-10- C6H50*H* Initial 0 0 Change Equilibrium [H+] = pH= C6H5OH 0.16M
