Unformatted text preview: NaCl to come out of solution because additional chloride ions were added, resulting in a shift to the reactants. Adding Fe3+ and NCS- to [FeNCS2+] both caused more [FeNCS2+] to be created, resulting in a much darker red solution. Adding Ag+ removed the SCN- ion and resulted in less [FeNCS2+], making the solution a lighter red. Adding more NH4 + to its system resulted in a colorless solution, indicating an acidic pH, as the reaction shifted left and less OH- ions were created. Conclusion-LeChateliers Principle is easily observed in a system that is disturbed at equilibrium. Based on a balanced formula, one can predict how the system will react to counter the disturbance and in which direction it will shift....
