Barbital-Sodium Buffer pH 8.6
Barbital sodium buffer pH 8.6 is recognized as a specialized reagent in the laboratory field and is used for the preparation of buffer solutions in medical and histological diagnostics. By using barbital (a derivative of barbituric acid) and sodium 5,5-diethylbarbiturate, a stable and effective buffer system is provided, capable of keeping the pH of a solution constant. The properties of this buffer allow it to be used in a variety of experimental conditions where precise control of pH is necessary.
Chemically, the equilibrium between the acid (barbital) and its corresponding base (sodium 5,5-diethylbarbiturate) achieves a buffer range around pH 8.6. The addition of hydrochloric acid allows fine adjustment of the pH.
Calculated values:
Molarity (barbital): 0.012 mol/l
Molarity (sodium 5,5-diethylbarbiturate): 0.036 mol/l
Osmolarity: 0.048 osmol/l
Buffer capacity: within ±1 pH unit around pH 8.6.
