2. Provide the equilibrium that defines the pH of the following solutions. For solutions that involve more than one ionization or protonation, provide only the equilibrium that contributes most significantly to the solution pH. a. An aqueous solution prepared that is 0.10 M CH3COOH (Ka = 1.8 x 10-5) and 0.10 M CH3COONa (K₁ = 5.6 × 10-1⁰). b. An aqueous solution prepared that is 0.25 M in sodium citrate (citrate ion pictured below), Na3 C6H507 (Kb1 = 5.6 × 10-8; Kb2 5.9 × 10-10; Kb3 = 1.4 × 10-¹1) eve OH
