2. Carbonic acid (H:CO:) is widely used in the production of sodas, soft drinks, sparkling wines, and other aerated beverages. It is a diprotic acid with K 1 = 4.37 x 10- and K = 4.68 x 10-11. A Write the stepwise acid ionization equations for carbonic acid and the corresponding K, expressions. B. Calculate the concentration of all the species present at equilibrium in a 0.200 M carbonic acid solution Show a complete ICE table for each dissociation step. C. What is the pH of the 0.200 M carbonic acid solution in (B)? D. If you are to prepare a buffer solution with a pH of 11.00, which weak acid-conjugate base pair from carbonic acid should you use? Justify your answer. E. How are you going to prepare 50.00 ml of the buffer solution in (D)? The reagents that are provided to you are: 20.00 mL of 0.200 M sodium bicarbonate solution and a bottle of solid NaOH (MM= 39.997 g/mol). F. What will be the pH of the buffer solution prepared in (E) if 1.00 mL of 0.100 M HCl is added to it?
