Buffer Capacity

Buffer Capacity

Definition of Buffer Capacity Buffer Capacity (β): A quantitative measure of a buffer’s ability to resist pH changes. Mathematical Expression: $\beta = \frac{\Delta B}{\Delta{pH}}$ $\Delta \mathrm{pH}$ = amount (in moles per liter) of strong acid or base added. $\Delta B$ = change in pH resulting from the addition. Factors Affecting Buffer Capacities Concentration of Buffer … Read more

Buffer Equation

Buffer Equation

Buffer Equation, or Henderson-Hasselbalch equation, calculates the pH of a buffer solution based on the concentrations of its components.
