Video B: Click on the link above and watch the You Tube video. Pay careful attention as you record the data in the table below as the containers are not well labeled in this experiment. The labels given in the table are for reference when answering the questions. Label A B C D E Fe³+ (aq) + SCN- (aq) colorless pale yellow Action Initial Fe3+ solution Initial SCN solution Initial FeSCN²+ solution Mixture of Fe³+ and SCN- After adding Fe³+ to equilibrium mixture After adding potassium oxalate (K2C2O4) to (A) above After adding SCN to equilibrium mixture After adding silver nitrate (AgNO3) to (C) above After adding Fe(NO3)3 (s) to equilibrium mixture FeSCN²+ brownish red Color Direction Reaction Shifted XXXXX XXXXX XXXXX XXXXX

6) In terms of LeChâtelier's Principle, explain specifically why the reaction shifted when Fe³+ was added to the equilibrium mixture (labeled A).

7) In terms of LeChâtelier's Principle, explain specifically why the reaction shifted when SCN was added to the equilibrium mixture (labeled C).

8) Write the balanced net ion reaction that occurred between the silver ions and the thiocyanate ions (labeled D).

9) In terms of LeChâtelier's Principle, explain specifically why the reaction shifted when silver nitrate was added to the mixture (labeled D).

10) In terms of LeChâtelier's Principle, explain specifically why the reaction shifted when Fe(NO3)3 (s) was added to the equilibrium mixture (labeled E).
