Experiment 11 Date: 28-3-2011 Title: Interpretation of reaction by the Le Chatelier’s principle Objective: To determine the factors that affecting the equilibrium position Introduction: Le Chatelier’s principle states that if a system in equilibrium is subjected to a change‚ the equilibrium position of the system will shift in a direction to minimize the effect of the change. Iron(III) ions and thiocyanate ions (NCS-) react in solution to produce thiocyanatoiron(III) (FeNCS2+)‚ a
