Experiments

Here are experiments our science specialists have selected to support the IB* topic.

Recommended

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.

Recommended

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.

Recommended

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.
