Choice and Preparation of a Buffer System
1. Choosing the proper buffer solution
In Protein Precipitation, two liters of 5mM buffer solution with pH 5.2 is needed in the isolation of albumin. Which among the following buffer solution is best fitted for said purpose? Justify your answer.
Buffer solutions pKa
Acetate buffer 4.73
Tris- (hydroxymethy) aminomethane 8.08
Phosphate buffer 7.20
2. Preparation of the chosen buffer system
Calculate and measure the amounts (in grams if solid and in mL if liquid) of weak acid and conjugate base needed to be able to prepare the chosen buffer system in part A above. Express your answer in useful units (that is, prepare it from practical amounts or concentrations of starting materials).
