Use microscale titration to complete an acid–base neutralisation with sodium hydroxide in this class practical. Includes kit list and safety instructions.

In this experiment, students use a microscale titration apparatus – prepared from pipettes, a syringe and some rubber or plastic tubing – to carry out a titration, filling the ‘burette’ with hydrochloric acid and placing sodium hydroxide solution in a beaker. Students then try to calculate the exact concentration of the sodium hydroxide solution.
