Fe3+aq+ SCN-aq⇌FeSCN2+(aq) a) What does Le Chatelier’s principle say will occur if some Fe(NO3)3 is added to the system? (Fe(NO3)3 dissociates into independent Fe3+ and NO3- ions in solution.) b) In which direction will the system shift? c) When equilibrium is restored, how will the concentration of each substance compare to its concentration before the Fe(NO3)3 was added?   a) What does Le Chatelier’s principle say will occur if some sodium biphosphate is added to the system? (the HPO42-ion react with the Fe3+ion to produce FeHPO4+) b) In which direction will the system shift? c) When equilibrium is restored, how will the concentration of each substance compare to its concentration before the sodium biphosphate was added?
