You are asked to prepare a buffer to perform an enzymatic reaction. You have 100 mL 0.5 M lactic acid already and you need to add sodium lactate to make a buffer with pH of 4.5. How much salt in gram would you add to this 100 mL acid solution? The pKa of lactic acid = 3.86, and MW of sodium lactate is 112.

BUFFER PROBLEMS You are asked to prepare 1.2 L of a 0.05 M tris buffer at pH= 7.8. You start with the conjugate base form of tris (121 g/mol). How many grams of tris must you weigh out? How many mL of 6 M HCl (a strong acid) must you add to reach pH=7.8? The pKa for tris is 8.1.

You have an enzymatic reaction proceeding at the optimum pH and optimum temperature.

You have an enzymatic reaction proceeding at the optimum pH and optimum temperature. You add a competitive inhibitor to the reaction and notice that the reaction slows down. what can you do to speed the reaction up again? Add more inhibitor to speed up the reaction. Add more substrate; it will outcompete the inhibitor and increase the reaction rate. Increase the temperature. Increase the pH.
