Preparation of the 100 mM sodium citrate buffer (100 ml), pH 6.0?

Citric acid has three pKa’s:

pKa1 = 3.13

pKa2 = 4.72

pKa3 = 6.40

The desired buffer pH (100 mM sodium citrate buffer) is 6.0 which is close to pKa3 = 6.40, According to my understanding Pka3 exists between sodium citrate dibasic and tr Read more Read less
