Back titrations key words: activation energy, kinetics, antacid

When the reaction involves in a titration does not satisfies the conditions for a direct titration to be performed, it is possible to carryout a back titration.

If the reaction A & B’s slow (poor kinetics due to high activation energy), it cannot be analyzed using a direct titration. In such a case back titration is utilized by adding a known amount of the standard solution of A in excess to B and the excess of A is subsequently determined by using another titrant E, Where the reaction between A and E satisfies all conditions for a direct titration.

This process is called a back titration. Back titrations are very useful when the indicators recommended in the procedure are not available.
