The amino acid glycine is often used as the main ingredient of a buffer in biochemical experiments. The amino group of glycine, which has a p Ka of 9.6, can exist either in the protonated form NH3+or as the free base NH2, because of the reversible equilibrium RNH3+RNH2+H+ In what pH range can glycine be used as an effective In a 0.1M solution of glycine at pH9.0, what fraction of buffer due to its amino group? glycine has its amino group in the NH3+form? When 99% of the glycine is in its NH3+form, what is the numerical relation between the pH of the solution and the pKa of the amino group?
