Ryan O’Hearn Chemical Principles II Lab - 1011.206.43 Lab #7: Spectroscopic Determination of the Equilibrium Constant for [Fe 3+ (aq) +SCN - (aq)  FeSCN 2+ (aq) ] 04:49:13 Purpose Use visible spectroscopy to find the room temperature equilibrium constant for a reaction in an acidic aqueous solution. The reaction we will be observing is between the iron (III) ion (Fe 3+ ) and the thiocyanate ion (SCN - ) which forms ferric thiocyanate ion (FeSCN 2+ ). The equilibrium constant is when the reactants form products at the same rate that products are being broken back down into reactants again. Because of this, the reaction never actually stops. Procedure See “Chemistry 206 Lab: Chemical Principles II Laboratory,” “Lab #7: of the Equilibrium Constant for [Fe 3+ (aq) +SCN - (aq)  FeSCN 2+ (aq) ].” Data Tables, Graphs See Attached Excel Spreadsheet and Graph Sample Calculations Molarity of SCN - Solution (Question #1): M 1 x V 1 = M 2 x V 2 = M1 x V1V2 M 2 (0.002M x 0.010L) ÷ 0.09L = 2.22x10 -3 M SCN - Total Volume in Beaker (Question #2): mL Fe 3+ + mL SCN -

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
