Question

Why is back titration better than titration?

Answer 1

Answer:

Back titration is useful if the endpoint of the reverse titration is easier to identify than the endpoint of the normal titration.

Explanation:

In a direct titration, you add a standard titrant to the analyte until you reach the end point. In a back titration, you add an excess of standard titrant to the analyte, and then you titrate the excess titrant to determine how much is in excess.

The main difference between back titration and direct titration is that a back titration determines the concentration of the unknown by determining the remaining amount of the compound with a known concentration whereas a direct titration directly measures the concentration of the unknown compound.
