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 = 13 to get the same disinfectant power you would get by adding 1 g HOCl to 1 liter of water at pH = 2.0.

When chlorine is used for disinfection of drinking water, chloroform can be produced by the reaction...

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...

ENVIRONMENTAL ENGINEERING - When Cl2 gas is added to water for disinfection, it hydrolyzes with water to form HOCl. The combined concentrations of HOCl and OCl- is called “free chlorine” and the pKa for HOCl is 7.5. What percentage of the total disinfection power (measured as CT OCl- ) exists in the acid form at pH = 6? At pH = 7? Which form is a stronger disinfectant?

2. Chlorine is used as a disinfectant and is added in the form of sodium hypochlorite (NaOCl), which dissociates completely to Na+ and OCl-. The form of chlorine is then determined according to the known equilibrium reaction: HOCl ↔ H+ + OCl- with Ka = 10-7.54. A disinfection reactor treats a flow of 2,500 L/min. a. If the pH of the treated water is 9.6, what will the ratio of HOCl to OCl- (HOCl:OCl-) be? b. If operators decide that...
