In Protein Precipitation, two liters of 5mM buffer solution with pH 5.2  is needed in the isolation of albumin. Note that the pKa is 4.73. 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).  Show the solution step by step.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
