Experiment
The equilibrium between two coloured cobalt species
In this demonstration the equilibrium between two different coloured cobalt species is disturbed. Le Chatelier’s principle is used to predict a colour change.
-
Experiment
Exploring the chemistry of chromium, molybdenum and tungsten
Discover how transition elements differ in aspects of colour, precipitate formation, changes in oxidation state and equilibria. Includes kit list and safety instructions.
