Question

When Fe³⁺ and F⁻ are combined, the reaction Fe³⁺ +6F⁻ ⇄FeF₆³⁻ occurs. How does this reaction affect the reaction Fe³⁺ + SCN⁻ ⇄FeSCN²⁺ ? Justify your answer in terms of observations(picture below). Think about LeChatelier's principle

Equilibrium: LeChatelier's Principle and the Determination of an Equilibrium Constant Report Sheet Show a sample calculation on a separate piece of paper for all quantities marked with a "*". A. Le Chatelier's Principle: Fe3+ + SCN- What evidence is there of a chemical reaction? color cho color of Fe3+: clear color of SCN : clear color of FeSCN2+: red orange What change did you observe when you added more SCN to the mixture? dark red Trust What change did you observe when you added more Fe3+ to the mixture? dar k What change did you observe when you increased the temperature of the mixture? light orange What change did you observe when you decreased the temperature of the mixture? What change did you observe when you added F to the mixture? more you orange add it turns a light yellow clear What change did you observe when you added Fe3+ to the mixture after adding F"? it turns back more orange
