Homework Answers
A) if you add more Fe+3 concentration of Fe+3 ion increases equilibrium shifts to forward direction
B) if you remove SCN-, concentration of SCN- ion decreases equilibrium shifts to backward direction
C) if you remove FeSCN+2, concentration of FeSCN+2 decreases equilibrium shifts to forward direction
D) if you add more Fe+3 and remove FeSCN+3 that is favours to forward direction
See A and C
E) if you remove Fe+3 and remove FeSCN+2 both the concentration decreases. So, no effect on equilibrium.
Thank you ?

2. The reaction Fe3+ (aq) + SCN (aq) → FeSCN2+ (aq) produces a dark red color resulting from the formation of FeSCN2+. a. How does the color change if you add more SCN to a solution at equilibrium? (lighter or darker) b. How does the color change if you remove Fe3+ by reacting it with fluoride ions? c. If a reaction proceeds forward when you heat it, and reverse when you cool it, the reaction is [endothermic exothermic).

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.
