Equilibrium and LeChatelier's Principle
In this experiment you will be shown a series of equilibrium systems and asked to apply certain "stresses" to the systems.
The results of applying the stress will then be shown to you. For each system, record:
(a) The name of the equilibrium system
Include the reaction as well.
(b) Your observations
This means a color change, a precipitate formed or some like statement. For example, "the red solution turned green". Do not use this part to state what chemical change occurred. For example, you should not say "more cobalt ion was formed".
(c) What you think happened chemically
State what chemical reaction occurred or species was formed that resulted in your observation. For example, "by adding chloride ion to the solution it shifted the equilibrium to the left which caused more CoCl4-2 ion to be formed. Since this ion is blue, the solution became more blue."
