Le Châtelier's Principle
Investigate how a chemical equilibrium responds when the concentrations of the species involved in the reaction change and when the temperature changes.

Laborinformationen
Prepare a solution of cobalt(II) chloride hexahydrate, predict each equilibrium shift and compare the reversible colour changes observed in real laboratory recordings.
What the student does
- Prepares a reference solution of cobalt(II) chloride hexahydrate and reviews the key aspects of the experimental procedure.
- Analyses the effect of adding hydrochloric acid to increase chloride concentration or water to change the equilibrium.
- Investigates the effect of temperature through heating and cooling.
- Predicts the direction of each equilibrium shift before observing the real experiment.
- Uses the observed colour changes to interpret the equilibrium shift and justify conclusions.
The activity includes guided predictions, immediate formative feedback and a final review of the main conclusions about the effects of concentration and temperature on chemical equilibria.
