A 135 G Sample of Ammonium Chloride Is Added to Sufficient

A 1.35 g sample of ammonium chloride is added to sufficient water to give 150.0 mL of solution. Several reactions occur. Which of the following will determine the pH of the solution?

A) 2H₂O $\rightleftharpoons$ H₃O⁺ + OH^-
B) NH₄⁺ + H₂O $\rightleftharpoons$ NH₃ + H₃O⁺
C) NH₃ + H₂O $\rightleftharpoons$ NH₂^- + H₃O⁺
D) NH₄Cl $\rarr$ NH₄⁺ + Cl^-
E) NH₃ + H₂O $\rarr$ OH^- + NH₄⁺
