4. An engineer at a drinking water treament plant wants to study disinfection by hypochlorous acid. They prepare a solution of IHOCl in water by adding 75mgHHCl to a volumetric flask and adding water to the 2.0L mark. The final pH is measured to be 7.5. Assume the temperature is 25C. The K, of this resction is 7.54. a. What are the concentrations of HOCl and OCl2 (ro poims) b. What percent of the HOCl is dissociated? (s poimts) c. Observe the following pC-pH diagram. At what pH do you expect the beaker to contain 101MOCI ? Write your answer and circle it on the graph. Also circle the pKa on the plot 6 noinss
