Ph with kb
WebWhat is the K b Formula? The basic dissociation constant is Kb. In water, the base dissociation constant is a measurement of how thoroughly a base dissociates into its component ions. When predicting whether a species would donate or accept protons at a certain pH value, Ka, pKa, Kb, and pKb are the most useful.
