Montgomery College, Rockville 11. Determine whether the following systems have pH 7, or pH- 7. For each, complete the reaction and identify whether the reactants (R) or products (P) will predominate, and explain your choice. All species are aqueous unless otherwise noted. pHO7Reactants Favored: Explain your choice of R or P R or P NH4+ CO Kb for NH, 1.8 x10Ka for NH4-5.6x10 P Ka for HCO-5.6 x 101 Kb for Co 1.8 x10 Of the two acids, NH4' is stronger, and of the two bases, co, 2 is stronger. Therefore, products are favored Complete the equation NH4+ + CO32-= NH3 + HCO' acid base conj. base conj. acid Kb for NH3-1.8 x10; Ka for HCO,-5.6 x 10-11 since Kb > Ka, solution is basic (pH>7) a. H2SO4 H2o(e) Complete the equation H2SO4 + H20(1) b. NHy + H20(e) Complete the equation NH,+ H0(e) NH4 +HO(e) C. Complete the equation NH4+ + H20(1) d. NH3 + HF Complete the equation NH3 + HF
