11.13 Find m(H3O+) in a 0.10 mol/kg solution of NaCHO in water at 25C, given that Ka == 1.75 x 10-5 mol/kg for HC2H3O2 at 25C. (Hint: The acetate ion is a base and reacts with water as follows: C2H3O2 + H2O = HC2H3O2 + OH.) Show that the equilibrium constant for this reaction is K = Kw/K. Neglect the OH coming from the ionization of water. 11.13 Find m(H3O+) in a 0.10 mol/kg solution of NaCHO in water at 25C, given that Ka == 1.75 x 10-5 mol/kg for HC2H3O2 at 25C.
