Experiments
Here are experiments our science specialists have selected to support the IB* topic.
An Oxidation-Reduction Titration: The Reaction of Fe2+ and Ce4+
Experiment #8 from Advanced Chemistry with Vernier
In this experiment, you will
- Conduct the potentiometric titration of the reaction between ferrous ammonium sulfate hexahydrate and ammonium cerium (IV) nitrate.
- Measure the potential change of the reaction.
- Determine the molar concentration of iron (II) ions in a sample of ferrous ammonium sulfate hexahydrate.
Electrochemistry: Voltaic Cells
Experiment #20 from Advanced Chemistry with Vernier
In this experiment, you will
- Prepare a Cu-Pb voltaic cell and measure its potential.
- Test two voltaic cells that use unknown metal electrodes and identify the metals.
- Prepare a copper concentration cell and measure its potential.
- Prepare a lead concentration cell and measure its potential.
- Use the Nernst equation to calculate the Ksp of PbI2.
Electroplating
Experiment #21 from Advanced Chemistry with Vernier
In this experiment, you will
- Prepare and operate an electrochemical cell to plate copper onto a brass surface.
- Measure the amount of copper that was deposited in the electroplating process.
