- The pH of a 0.70 M solution of propanoic acid (HC,H,0,) is measured to be 2.51. Calculate the acid dissociation constant K, of propanoic acid. Round your answer to 2 significant digits. aYour consulting firm wants you to oversee the swimming pool disinfection arm of their business. Your new boss thinks that switching disinfectants from Cl2 gas to bleach (NaOCl) will save cost by eliminating engineering safety controls for Cl2 gas storage. The total acid or conjugate base is added to swimming pools at a concentration of 5*10^-3 M. Assuming activity coefficient = 1, algebraically calculate the pH of the pool where 5*10^-3 M of NaOCl is added. For any simplifications you make, include checks of your assumptions to validate your calculations. Use alpha values, Use Strong-weak acid assumptionFor each of the pH values listed in the first column, calculate and record the corresponding hydronium and hydroxide concentrations.
