Experiments
Here are experiments our science specialists have selected to support this IB* topic.
Determining the Enthalpy of a Chemical Reaction
Experiment #13 from Advanced Chemistry with Vernier
In this experiment, you will
- Use Hess’s law to determine the enthalpy change of the reaction between aqueous ammonia and aqueous hydrochloric acid.
- Compare your calculated enthalpy change with the experimental results.
Burning Accelerants
Experiment #6 from Forensic Chemistry Experiments
- Compare the heat of combustion for two accelerants: the crime scene evidence and samples from arson suspects.
- Calculate the heat of combustion in kJ/g.
- Use your data and calculations to identify which suspect had the same accelerant as that used at the crime scene.
