Question
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?
