How to measure the endpoint of a titration?
There are different ways to measure the endpoint of a titration:
· Using an indicator: This is a substance that changes colour at a certain pH. For example, acid-base indicator phenolphthalein changes colour depending on the pH. In this case, the endpoint is reached when the colour changes.
· Using a potentiometer: This instrument measures the electrode potential, which changes abruptly at the endpoint in redox titrations.
· Using a pH meter: In this case, the endpoint is determined when a sudden change in pH occurs. This is more accurate than using a pH indicator.
· Measuring conductivity: Ion concentration can change suddenly during a titration, which in turn changes conductivity.
· By formation of a precipitate: In this case, the endpoint is when the precipitate appears. Sometimes, cloudy solutions make it difficult to determine the endpoint accurately, so back titrations are used instead.
· Using an isothermal titration calorimeter or through thermometric titrimetry: This approach measures the heat either produced or consumed during a reaction. This process is often used in biochemical titrations involving enzymes.
· By spectroscopy: this method relies on changes in light absorption to determine the endpoint.
· By amperometry: Finally, this process measures the current produced during the reaction, and the endpoint is determined when the current changes. This method is most useful in redox reactions, when the excess titrant can be reduced.
