3. Displacement (Substitution) Titration

❖ In this type, a very weak acid or base is displaced from its salt by

a strong acid or base.

❖ Typical examples include the titration of sodium carbonate or sodium borate (borax)

against standard HCl.

Na CO + 2 HCl → 2 NaCl + H O + CO
2 3 2 2

HCl (strong acid) displaces carbonic acid (very weak acid) in its salt
