Experiments
Here are experiments our science specialists have selected to support the IB* topic.
Fractional Distillation
Experiment #8 from Chemistry with Vernier
In this experiment, you will
- Observe what happens when a liquid-liquid mixture is heated and allowed to boil over a period of time.
- Determine percent composition of ethanol and water in the fraction from its density.
Effect of Temperature on Solubility of a Salt
Experiment #12 from Chemistry with Vernier
In this experiment, you will
- Study the effect of changing temperature on the amount of solute that will dissolve in a given amount of water.
- Plot a solubility curve.
Liquid Chromatography
Experiment #18 from Advanced Chemistry with Vernier
In this experiment, you will
- Conduct an isocratic, liquid-chromatographic separation.
- Conduct a step gradient, liquid-chromatographic separation.
- Complete the necessary measurements and calculations to evaluate the components of a mixture that have been separated by liquid chromatography.
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.
- Calculate the amount of energy used to complete the electroplating process.
Determining Avogadro's Number
Experiment #31 from Advanced Chemistry with Vernier
In this experiment, you will
- Prepare an electrochemical cell to oxidize a copper electrode.
- Measure the amount of copper that was deposited in the electroplating process and determine the average current used.
- Calculate a value for Avogadro’s number and compare it to the accepted value.
