According to Le Châtelier, if a stress (change in concentration or temperature) is applied to this system, the equilibrium will shift to counteract that change. Chemicals: (Iron(III) nitrate), (Potassium thiocyanate), Na2HPO4cap N a sub 2 cap H cap P cap O sub 4 AgNO3cap A g cap N cap O sub 3 (for removing ions), distilled water.
To write your lab report for the experiment, you should focus on how external "stresses"—like concentration or temperature—shift the balance between the reactants and the reddish-brown product. FeSCN2 В Equilbrium - LeChatelier's Principle Lab Part 1
