Hypochlorous acid, HOCl is a weak acid commonly used as a bleaching agent. The acid-dissociation constant, Ka, for the reaction of HOCl with water is 3.2*10E-8.
(A) Calculate the (H3O+) of a .14 molar solution of HOCL.
(B) Write the correctly balanced net ionic equation for the reaction the occurs NaOCl is dissolved in water and calculate the numerical value of equilibrium constant for this reaction.
(C) Calculate the pH of a solution made by combining 40.0 milliliters of .14-molar HOCl and 5.0 milliliters of .56-molar NaOH.
(D) How many grams of solid NaOCl must be added to 50.0 milliliters of .20-molar HOCl to obtain a buffer solution that has a pH of 7.49? Assume that the addition of the solid NaOCl results in a negligible change in volumes.
