In this experiment, see Le Chatelier's Principle by observing physical changes to solutions as systems are stressed.

Le Chatelier's Principle is a qualitative rule that allows the prediction of the effect of temperature, pressure and concentration changes on chemical reactions. The principle states: A chemical system at equilibrium when stressed by external forces will adjust in such a way as to minimize that stress.
