membranes.comdioxide gas will react with water to form a very weak carbonic acid, but this is not considered to be part of total alkalinity since it has no acid buffering capacity. Carbon dioxide and bicarbonate are in a balance between the pH range of 4.2 to 4.5 at the low end and 8.2-8.4 at the high end. At a pH of 4.2 to 4.5 or

www.who.int2. CHEMISTRY OF DISINFECTANTS AND DISINFECTANT BY-PRODUCTS 2.1 Background The use of chlorine (Cl 2) as a water disinfectant has come under scrutiny because of its potential to react with natural organic matter (NOM) and form chlorinated disinfectant by-products (DBPs). Within this context, NOM serves as the organic DBP precursor, whereas bro-
