His equation was incomplete without the solid calculations into it provided by Hasselbalch. Karl Albert Hasselbalch (1874-1962) was a chemist who studied pH closely. He also studied blood and reactions that took place with oxygen, to put in the simplest of terms. read more
In chemistry, the Henderson–Hasselbalch equation describes the derivation of pH as a measure of acidity (using pK a, the negative log of the acid dissociation constant) in biological and chemical systems. read more
Take a look at the Henderson-Hasselbalch equation and a worked example that explains how to apply the equation. read more
