11. In titrating 0.20 M hydrochloric acid, HCl, with 0.20 M NaOH at 25°C, the solution at the equivalence point is (Cl: 35.45 g/mol): (A) 0.20 M NaCl； (B) very acidic； (C) slightly acidic； (D) 0.10 M HCl and 0.20 M NaOH； (E) 0.10 M NaCl

12. Consider a solution containing the following cations: Na⁺, and Ag⁺. Treatment of the solution with dilute HCl followed by saturation with H2S results in formation of precipitate(s). Which ions still remain in solution ? (A) Ag⁺ only； (B) Na⁺, ； (C) Ag⁺ and ； (D) Na⁺, , and ； (E) Na⁺ only

13. A mixture of hydrogen and chlorine remains unreacted until it is exposed to ultraviolet light from a burning magnesium strip. Then the following reaction occurs very rapidly:  → ∆G = -45.54 kJ； ∆H = -44.12 kJ； ∆S = -4.76 J/K  Which of the following is consistent with this information? (A) The reactants are thermodynamically more stable than the products. (B) The reaction has a small equilibrium constant. (C) The ultraviolet light raises the temperature of the system and makes the reaction more favorable. (D) The negative value for ∆S slows down the reaction. (E) The reaction is spontaneous, but the reactants are kinetically stable.
