Titration

A titration is a type of chemistry experiment in which colour, temperature or other change are used to determine the content or characteristics of an unknown chemical. We can use this method to work out the acidity/alkalinity of a chemical and how much of a known chemical it is needed to neutralise it (known as the reaction endpoint).

The most common forms of titration are acid-base titrations and redox titrations. In acid-base titrations, acids and bases are neutralised. An indicator is usually used to determine the point at which all the substance analysed has been neutralised. Indicators are not required when the constituents have intense colours that change once the reaction is completed, such as in certain redox titrations.
