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.
In this experiment, the aim is to determine the heats of combustion of alcohols, specifically butan-1-ol. The experiment involves burning a measured mass of an alcohol in a spirit lamp and transferring the heat energy released to a calorimeter containing water. From the resulting temperature rise, the heat of combustion can be calculated. The apparatus used must be calibrated using an alcohol with a known heat of combustion due to factors such as the heat energy lost to the surrounding air and the heat capacity of the calorimeter. Safety precautions must also be taken due to the flammability and potential toxicity of the alcohols. The experiment provides an opportunity to calculate the specific heat capacity of the calorimeter and determine the enthalpy change of butan-1-ol. Calculations can be made to determine the percentage difference between experimental values and data book values and to explain why there may be a difference.
