Experiments
Here are experiments our science specialists have selected to support the IB* topic.
The Determination of an Equilibrium Constant
Experiment #10 from Advanced Chemistry with Vernier
In this experiment, you will
- Prepare and test standard solutions of FeSCN2+ in equilibrium.
- Test solutions of SCN− of unknown molar concentration.
- Determine the molar concentrations of the ions present in an equilibrium system.
- Determine the value of the equilibrium constant, Keq, for the reaction.
Determining the Ksp of Calcium Hydroxide
Experiment #23 from Advanced Chemistry with Vernier
In this experiment, you will
- Titrate a saturated Ca(OH)2 solution with a standard HCl solution.
- Determine the [OH−] for the saturated Ca(OH)2 solution.
- Calculate the Ksp of Ca(OH)2.
Determining Ka by the Half-Titration of a Weak Acid
Experiment #24 from Advanced Chemistry with Vernier
In this experiment, you will
- Conduct a reaction between solutions of a weak acid and sodium hydroxide.
- Determine the half-titration point of an acid-base reaction.
- Calculate the pKa and the Ka for the weak acid.
Investigating LeChatelier’s Principle
Experiment #13 from Vernier Chemistry Investigations for Use with AP* Chemistry
This investigation will take advantage of your knowledge of LeChatelier’s Principle. It may also deepen understanding of equilibrium in general. The objective is to prepare six equilibrium systems in a set of test tubes that display the colors red, orange, yellow, green, blue, and violet.
