2. The stock solution at equilibrium used in teat tuba #4 contains Fe"(aq), SCN-(aq) and FeSCNPtaq). When NaOH was added to test iube #4 a slaft in the equilibrium was observed. What chemical species in the stock solution reacted with NEOH Vilite the balanced chemical reaction associated with the change observed from the addition NaOH to iest tube #4? Explain in terms of LeChatelier's Principle the observed results from the addition of 0.1 M KSCN to test...

The Common Ion Effect Reaction: Fe3+ + SCN <> Fe(SCN)2+ 1. After the addition of 0.1 M KSCN to test tube 2, what is the color of the solution? How does the addition of KSCN affect the equilibrium of the reaction above? How does this relate to the change, if any, in the color of the solution? Include equations for reactions in your explanation. Color: dark red After the addition of 0.1 M Fe(NO3)3 to test tube 2, what is...

My question is #2 for the reaction Fe3+ (aq) + SCN- (aq)
FeSCN2+ (aq). The goal is to predict the color change (darker or
lighter) for test tubes 2-8. I have attached the supplemental
sheets given to help with the problem. The test tubes 2-8 are being
manipulated either by temperature or things being added which can
be seen by one of the pictures.
