Displacement titrations (Key words: Bronsted bases, acetates, carbonates, borates)

Neutralization of anions of weak acids (Bronsted Bases) with strong acids

Theory


Titrations are also possible with weak bases (Bronsted bases) such as acetates, carbonates, borate ions. Here the OH- produced due to hydrolysis of the salt will react with the strong acid.

The weak acetic acid was apparently displaced by the strong HCl, and the process was referred to as displacement titration.
The so called titration of solutions of hydrolysis is merely the titration of a weak base with a strong acid (highly ionized).
