Carbonic acid is a weak di-protic acid, which constitutes an important buffer system in the blood. There, it can dissociate two different protons at two different pka’s. These pka values are 6.4 and 10.2  a) Research the chemistry of this system in your textbook and provide the balanced equilibrium reactions. Start with the formation of carbonic acid from carbondioxide and water and show the reactions where protons dissociate. For each step provide both the chemical formulas and the names of the chemical components. Indicate the above pka values for the appropriate equilibrium reactions b) Provide both the chemical formulas and the names of all molecules shown in a) that can act as i) weak acid and ii) conjugate base at the respective pka values
