In chemistrythe Henderson—Hasselbalch equation [1] [2] describes the derivation of pH as a measure of acidity using p K athe negative log of the acid dissociation constant in biological and chemical systems.

For ionizable groups that are able to deprotonate to a charge of -1 e. There are some significant approximations implicit in the Henderson—Hasselbalch equation. Yenderson is useful in arterial blood gasbut these usually state p CO 2that is, the partial pressure of carbon dioxiderather eccuacion H 2 CO 3.

However, these are related by the equation: The Henderson Hasselbalch equation was developed independently by the American biological chemist son and the Swedish physiologist K.

For the standard base equation: From Wikipedia, the free encyclopedia. Creating downloadable prezi, be patient. This article needs attention from an expert in Chemistry.

The Hsselbach equation is derived from the acid dissociation constant equation by the following steps: Julian—Gregorian uncertainty Use dmy dates from September Hendersln article needs additional citations for verification. The dissociation of water and relative water concentration itself is neglected as well.

Julian—Gregorian uncertainty Use dmy dates from September Retrieved 27 March Sometimes these other units are more convenient to use. InLawrence Joseph Henderson wrote an equation describing the use of carbonic acid as a buffer solution. The genderson is also useful for estimating the pH of a buffer solution and finding the equilibrium pH in acid-base reactions it is widely used to calculate the isoelectric point of proteins.

The equation is also useful for estimating the pH of a buffer solution and finding the equilibrium pH in acid-base reactions it is widely used to calculate the isoelectric point of proteins.

Later, Karl Albert Hasselbalch re-expressed that formula in logarithmic terms, resulting in the Henderson—Hasselbalch equation.
