Questions 8. Acid can dissociate in solution, which characterized by dissociation constant (Ka). Polyprotic acids can dissociate multiple times, which associated by multiple dissociation constant (Kal, Ka2, Ka3 etc.) CO2 dissolve in water forms carbonic acid H2CO3 CO2 (aq) = H2CO3 (aq) K=1.7x10-3 H2CO3 (aq) = HCO;" (aq) + H*(aq) Kal=2.5x104 HCO3 (aqg) = CO3 (aq) + H* (aq) Ka2= 5.0×10-11 (a) For soda water, the CO2 concentration is 6g/L and the pH is 4. Calculate the equilibrium molar concentration of HCO3 and CO32- (b) It is known that the CO2 concentration in air is 387ppm, and the CO2 Henry constant KH= 29.4 atm/mol. The second dissociation is negligible. Calculate the pH of the pure water after equilibrium in air
