Enthalpy – Thermometric titration

Enthalpy – Thermometric titration

Thermometric titration is a powerful technique used to determine the concentration of acids and bases by measuring the temperature change during a chemical reaction. In this article, we explore the process of thermometric titration and how it is used to calculate the enthalpy change of neutralization for hydrochloric acid and ethanoic acid using a standard solution of sodium hydroxide. We outline the required materials, the titration procedure, and the calculation process involved. Additionally, we answer common questions about the enthalpy change of neutralization, the experimental results for hydrochloric acid, and the heats of neutralization for weak acids and bases.

In this experiment, students will have the opportunity to develop their practical and analytical skills, which are essential for the IA internal assessment or practical exams. By investigating the enthalpy change that occurs when solid ammonium chloride dissolves in water, students will learn how to conduct a scientific experiment using calorimetry techniques. This experiment will also allow students to calculate the enthalpy change and analyze their results, which will help them to understand the importance of accuracy and precision in scientific measurements. By engaging in this experiment, students will gain valuable experience in carrying out practical chemistry experiments and will be better equipped to succeed in their internal assessments or practical exams.
