Define the citrate buffer

Reference no: EM13179538

You are fortunate to land a research position with Dr. Xavier Wray. Your first day in the lab the good doctor asks you to make a liter of 0.1 M citrate buffer pH 3.5 that you will need for the big extract procedure he will show you how to do after lunch. The 3 pKa values for citrate are 3.09, 4.75, and 5.41. You find the trisodium citrate on the reagent shelf and calculate the amount you%u2019ll need for the solution. While you%u2019re dissolving the sodium citrate you discover there%u2019s only 100 mls of 1 M (i.e., 1 N)hydrochloric acid available. Is there enough HCl to make the solution you need?
