When cl2 gas is added to water during disinfection ofwater


When Cl2 gas is added to water during disinfection ofwater, it hydrolyzes with water to form HOCl. The power of acidHOCl is 88 times better than its conjugate base, OCl- .The pKa for HOCl is 7.5

(a) What percentage of the total disinfection power (HOCl +OCl- ) exists in the acid form at pH = 6?

(b) At pH = 7

relevant reactions:

H2O + Cl2 <---> HOCl + HCl

HOCl <----> H+ + OCl-
