Question

121 F19 Homework Due to Workshop Leader by end of day 11.22.19 Someone found a smashed box of smelling salts in a storage closet of Fauver Stadium. The field hockey team manager, being a chemistry pro, knew that if she could convert all of the ammonia (NH3) found in the smelling salts into an ammonium salt (NH4* + X), she could get rid of the horrid smell. If the closet contained 100 mL of 1.0 M NH3 solution and the field hockey team manager/chemistry pro added 100 mL of a 1.0 M solution of H2SO4 ... Kb for NH3 = 1.73.10-5, Ka H,so = 1000, Ka HS0 = 1.2.10-2 a. Provide a Keg value for each of the following reactions H20, + NHÀ PHỐ0 + NH HS0; + NH3 + so?- + NH NH, + H20 + OH- + NHẸ NH + H20 2 NH3 + H30+ so2- +H,02HSO, + OH- b. Using the equilibrium constants above, where do you start in sorting out what is happening in the solution?
