Fe3+(aq it. yellow) + SCN(aq colorless) [FeSCN]2+(aq. red) a student studying this equilibrium begins with an equilibrium mixture that is light pink. what change will the student observe when a solution containing Fe3+ ion is added to this mixture?

Question

Fe3+(aq it. yellow) + SCN(aq colorless) <--> [FeSCN]2+(aq. red)     

a student studying this equilibrium begins with an equilibrium mixture that is light pink.
what change will the student observe when a solution containing Fe3+ ion is added to this mixture?

matt101 · Answer

If you add Fe3+ ions, which way will the reaction shift?

anonymous · Answer

it favors a forward reaction I think?

matt101 · Answer

Right! So what would happen to the solution?

anonymous · Answer

would the solution become darker, or more red?

matt101 · Answer

Exactly right!

anonymous · Answer

thank you! so is this consistent with Le Chateliers principle because by adding more reactant the equilibrium favors the forward reaction to the right?

matt101 · Answer

Yup it's just an application of Le Chatelier's Principle
