Drinking water is often disinfected with Cl2, which hydrolyzes to form HClO, a weak acid but powerful disinfectant: Cl2(aq) + 2 H2O(l) HClO(aq) + H3O+(aq) + Cl−(aq) The fraction of HClO in solution is defined as [HClO] / [HClO] + [ClO−]
(a) What is the fraction of HClO at pH 7.00 (Ka of HClO = 2.9×10−8)?
(b) What is the fraction at pH 8.50?
