Le Châtelier's principle states that chemical systems at equilibrium shift in the direction that opposes the change when a change occurs that disturbs the equilibrium (DiGiuseppe, Haberer, Salciccioli, Sanader, & Vavitsas, 2012, p. 439). Le Chatelier's Principle Lab: Cobalt Complex Ions Complex ions are an advanced topic in chemistry that are important for inorganic chemistry. In other words, it can be used to predict the direction of a chemical reaction in response to a change in conditions of temperature, concentration, volume, or pressure. Le Chatelier's principle (LCP) and the concept of equilibrium are tricky topics for many students, and LCP is still present in many exam specifications.
