Experiments
Here are experiments our science specialists have selected to support the 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.
