Answer to Question #69790 in General Chemistry for Lindsey

Question

1. When Fe3+ and SCN- react to form an equilibrium with FeSCN2+ , what happens to the concentration of Fe3+? Explain your answer.




2. How are the numbers of moles of FeSCN2+ produced and the number of moles of Fe3+ used up related to each other?




3. In this experiment we assume that the complex ion formed is iron thiocyanate, FeSCN2+. It is however, possible to form Fe(SCN)2+ under some circumstances.

a. Write a reaction for the formation of this alternative ion.




b. Write the equilibrium constant expression for this reaction.
