Chem 125 Winter Name: ___________________________ Date of Experiment: ________________ Partner: __________________________ Lab (circle one): W 12 – 3 R 8 – 11 R 3 – 6 F 12 – 3 Partner: __________________________ Experiment 6: Determination of an Equilibrium Constant Lab Report Due: Beginning of lab during week 7 (week of February 13 th to 17 th ). Part 1: Absorbance of Standard Solutions Concentration of FeSCN 2+ in stock solution: .00015 In the space below, show how you calculated the concentration of FeSCN 2+ in the stock solution. C 1 V 1 = C 2 V 2 .002(3)= C 2 (40) C 2 =.00015 In the table below, record the results of your observations for each of the standard solutions you made. Title this table (in the space below) and use units where appropriate. Raw Data Showing the Volumes, Absorbance, and Amount of [FeSCN 2+ ] in each tube Tube No. Volume of FeSCN 2+ stock solution Volume of HNO 3 solution [FeSCN 2+ ] in Standard Solutions Absorbance 1 1 4 .00003 .149 2 2 3 .00006 .347 3 3 2 .00009 .554 4 4 1 .00012 .768 5 5 0 .00015 .966 In the space below, show how you calculated the [FeSCN 2+ ] for standard tube #2: C 1 V 1 = C 2 V 2 .00015(2)= C 2 (5) C 2 =.00006
