When Chlorine gas is used to disinfect drinking water, it hydrolyzes with the water to form hypochlorous acid (HOCl, pKa = 7.54), which is a powerful disinfectant. However, when the acid dissociates to its conjugate base, it becomes a less effective disinfectant. The disinfection power of the acid is 88 times better than its conjugate base, OCl-, on a per-mole basis. Calculate the mass of hypochlorous acid you would need to add to 1 liter of water at pH =...

When chlorine is used for disinfection of drinking water, chloroform can be produced by the reaction of chlorine with residual organics in the water. For chloroform, RfDoral = 0.01 mg/kg/d and SForal = 0.0061 1/(mg/kg/d). Estimate the ingestion intake rate for non-carcinogenic and carcinogenic effects on an adult resident of a home receiving tap water with an average chloroform concentration of 65 mg/L. Calculate the potential non-carcinogenic and carcinogenic health risks associated with this ingestion rate. Are the risks presented...
