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). Describe how you would make 1.5L of the buffer using your newly constructed 1.0 M Tris stock solution, a 500 mM stock solution of NaCl, and a 1.0 M stock solution of DTT. Show all calculations.

Your goal is to make a buffer with a pH of 4.95 from acetic acid and sodium acetate. Assume the pKa for acetic acid is 4.74. What is the volume of acetic acid added to make your buffer? Report your answer to the tenths place. To do this, we use the Henderson-Hasselbach Equation pH = pkA + log (base/acid) where pkA = 4.74 for acetic acid, pH = target pH and [base] /[acid] = x/(1-x) since we don't know the concentration of the base, we will call it x the acid is just 1-x, assuming the two add up to 100% solve for x, and then you know the mL of base and acid to add.
