WebThe pH of a buffer depends on the ratio [base]/[acid] rather than on the particular concentration of a specific solution. The exact ratio of the base to the acid for a desired pH can be determined from the K a value and the Henderson-Hasselbalch equation. For example: Suppose you wish to prepare a buffer solution to keep the pH at 4.30.
