Titration Calculations [H]

This lesson covers titration calculations as required by the AQA GCSE Chemistry specification (4.3.3). This is Higher Tier only content. Titrations are used to find the concentration of an unknown solution by reacting it with a solution of known concentration. You need to be able to process titration results, identify concordant values, and carry out calculations involving moles, concentration, and volume.

What Is a Titration?

A titration is an experimental technique used to determine the exact volume of one solution needed to react completely with a known volume of another solution. Typically, an acid is neutralised by a base (or vice versa), and an indicator is used to show the end point — the moment the reaction is complete.
