Phosphate buffered saline (PBS) is a buffer solution commonly used in biological research. The buffer helps to maintain a constant pH. The osmolality and ion concentrations of the solution usually match those of the human body. A) You need to prepare a stock solution at pH 7.00 with KH2PO4 and Na2HPO4 (pKa =7.21). What would be the respective concentration of these substances if you wish to obtain the final phosphate concentration [HPO4 −2 ] + [H2PO4 − ] = 0.3...

20. Properties of a Buffer The amino acid glycine is often used as the main ingredient of a buffer in biochemical experi- ments. The amino group of glycine, which has a pKa of 9.6, can exist either in the protonated form (-NH3 or as the free base (-NH2), because of the reversible equilibrium (a) In what pH range can glycine be used as an effective buffer due to its amino group? (b) In a 0.1 M solution of glycine at...
