Influence of a change in temperature on the chemical equilibrium

LC3.5.2.1

To carry out all experiments from this subject area, we offer you a complete set: CLICK HERE

Description

The chemical equilibrium can be influenced by several factors according to Le Chatelier's principle. In this experiment the students make a blue and a green copper complex. Both complexes can be transformed into each other by heating and cooling in an equilibrium reaction. In this way, the students experience the temperature dependence of chemical equilibria in this experiment.
