Ion speciation
text:
Speciation of ions refers to the changing concentration of varying forms of an ion as the pH of the solution changes. The pH of a solution of a monoprotic weak acid can be expressed in terms of the extent of dissociation. After rearranging the expression defining the acid dissociation constant, and putting pH = −log10[H+], one obtains This is a form of the Henderson-Hasselbalch equation. It can be deduced from this expression that when the acid is 1 % dissociated, that is, when [AH]/[A−] = 100,
