Le Chatelier's Principle Le Chatelier's principle states that when a system in chemical equilibrium is disturbed by a change in temperature, pressure, or concentration, the system will shift in equilibrium composition in a way that tends to counteract this change of variable The three ways that affect this change in equilibrium include:
Le Chatelier’s Principle Description: Le Chatelier’s principle is demonstrated by either invoking a color change of anhydrous (blue) CoCl 2 or hexahydrate (pink) CoCl 2•6H 2O OR by observing the color change involved with the conversion of the chromate ion to the dichromate ion by addition of acid or base Materials:
Le Chatelier’s Principle Introduction: In this experiment you will observe shifts in equilibrium systems when conditions such as concentration and temperature are changed You will explain the observed color changes of four reactions in terms of Le Chatelier’s principle Le Chatelier predicted how an equilibrium system would respond to

Le Châtelier’s Principle According to Le Châtelier’s Principle, when a system at equilibrium is subjected to a stress (a change in concentration, temperature, or pressure), the equilibrium will shift in the direction that tends to counteract the effect of the
Le Chatelier’s Principle states that “If a stress is applied to a reaction at equilibrium, the reaction will shift to offset the stress applied” The addition of hydrogen ions or hydroxide ions constitutes a stress, as does the removal of either ion, and so it can be
