A microscale acid–base titration

In this experiment, students use a microscale titration apparatus, referred to in the student sheets as a microscale burette – 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.

The downloadable resources include two levels of student worksheet (scaffolded and unscaffolded) with practical method and follow-up questions. Also included are lesson slides, teacher and technician notes containing answers to the questions on the student worksheets.
