Use this class practical to practise locating end-points in titration by measuring temperature during the reaction. Includes kit list and safety instructions.

In this experiment, students titrate sodium hydroxide solution with hydrochloric acid. By measuring the temperature change each time a portion of acid is added, students can determine the end-point of the titration, indicated by the highest temperature. They then use this information to calculate the concentration of the hydrochloric acid.
