Academics

When Cl2 is used as water disinfectant, the following reactions should be used to determine the concentration of different species.

Cl2(g) ------> Cl2 (aq) Kh = 8.0x10^-3 M

Cl2(aq) + H2o (l) -----> H+ (aq) + Cl(aq) + HOCl (aq) Kc= 4.5x10-4 M^2

HOCl (aq) ----> H+(aq) + OCl- (aq) Ka = 3.0x10^-8 M

Calculate the concentration of each species when pure water is treated with 100 ppm Cl2.
