In this short video, Paul Cook will show you Le Châtelier’s Principle by demonstrating the reversible equilibrium reaction by change of temperature using cobalt ions. Make sure to watch until the end for extra tips!
Le Chatelier’s principle describes how, when a dynamic equilibrium is disrupted by a change of pressure, temperature, volume or concentration, the position of equilibrium will shift to counteract any change and restore an equilibrium state.
The equilibrium reversible reaction of two-coloured cobalt species due to a change of temperature.
Le Chatelier’s principle, when the temperature has raised the equilibrium of the chloride ions in the solution will change and a blue complex of ions is formed in expense of the pink species.
Cooling the solution will reverse this reaction and the equilibrium moves to a pink complex of ions.
