The total carbonate pool in blood plasma (blood lacking red blood cells) is 0.025M and consists of both HCO3 and CO₂ (aq). The pka for the dissociation of H₂CO3 to produce HCO3 and H* at 37°C is 6.1. Because H₂CO3 is readily produced in blood from dissolved CO₂ (aq) + H2O (a reaction catalyzed by the enzyme carbonic andhydrase), CO₂ (aq) can be considered the conjugate acid and HCO3- the conjugate base in the bicarbonate buffering system. i. What is the ratio of HCO3 and CO₂ (aq) in blood plasma at pH of 7.4? ii. What are the individual concentrations of CO₂ (aq) and HCO3 under these same conditions?

Time to purify biochemisfunase! To do this, you’ll need to make MORE buffers. One of the buffers that you need to make requires 150 mM Tris (pH 8), 250 mM sodium chloride (NaCl) and 2 mM dithiothreitol (DTT, a reducing agent that prevents the formation of disulfide bonds in proteins). Your jolly postdoc friend wants you first to make 500 ml of a1.0M Tris stock solution before making the buffer. Describe how you would make this stock solution, and show all calculations.
