Theme: Balance a. Calculate the pH of a saturated carbon dioxide solution at 25C (soft drink), describe what would happen to the pH if we increase the temperature?

B. The formation of carbonic acid obeys the following chemical equilibrium CO2 (aq) + H2O H2CO3 (aq) Whose equilibrium constant is approximately: K = 1 x 10-3 Write the expression for the equilibrium constant and describe in which direction the equilibrium will be favored, towards the formation of products or reactants? Then deduce which substance will prevail in the solution, dissolved carbon dioxide or carbonic acid?

C. What will happen to the concentration of carbonic acid if more carbon dioxide is added?
