When chiorine (Cl2) gas is added to water during the disinfection of drinking water, it hydrolyzes with the water to formi hypochlorous acid (HOCII. The disinfection power of the acid HOCI is 88 times better than its conjugate base, OCI. The pka for HOCI is 7.5. Because the acicic, form is a much better disinfectant. you want to maintain 73% of the total molar concentration in this form. What minimurm pH shauld you targel? Enter your answer rounded to one decimal place. Hint: You'll need to set up a system of two equations.
