2. A 0.15 M solution of HCI is saturated with H₂S. For H₂S (aq), Ka,1 = 8.9 x 10-8 and Ka,2 = 1.2 x 10-13. In a solution saturated with H₂S (g) at 1 atm, [H₂S (aq)] is 0.10 M. What is the concentration of S²-? What is the concentration of HS-? a. b.

12. Carbonated water has a [H+Jeg = 3.2 × 10-4 M; this is the result of the dissociation of carbonic acid: H₂CO3 (ag) H+ (aq) + HCO3- (ag) Kc = 4.4 x 10-7 a. Set up the equilibrium constant expression for this acid dissociation. b. Calculate [H₂CO₂]ea. Hint: An ICE table may be handy. c. Carbonic acid is created by dissolving carbon dioxide in water. Given that the Henry's Law constant of carbon dioxide is 29.76 atm/M, what partial pressure of carbon dioxide is needed to make carbonated water?
