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.
By using activated charcoal to remove the indicator, this modified experiment demonstrates the neutralization of hydrochloric acid with sodium hydroxide and the separation of a soluble salt. The procedure can be used to investigate the stoichiometry of acid-base reactions and to determine the yield of a reaction.
