How many of the following combinations of reactants will react until more than 98% of the limiting quantity is used up? (a) CH₃COOH + H₂O (b) CH₃COO⁻ + H₂O (c) CH₃COO⁻ + H₃O⁺ (d) CH₃COOH + KOH (e) CH₃COOK + HCl(aq) (f) HCl(g) + H₂O (g) Cl⁻ + H₃O⁺ (h) Cl⁻ + H₂O (i) NH₄⁺ + KOH (j) NH₄⁺ + OH⁻ (k) NH₃ + H₂O (l) NH₃ + H₃O⁺ (m) NH₃ + HCl(aq) (n) K⁺ + OH⁻

Answer: 8

Solution

Reactions that go essentially to completion (strong acid/base reacting with a weak conjugate, or strong-acid/strong-base ionization): (c), (d), (e), (f), (i), (j), (l), (m) = 8
