CHEM 032 Experiment 3: Determination of the Equilibrium Name: ________________________ Constant for a Chemical Reaction Date: ________________________ E03-9 Calculations A. Preparation and Analysis of Calibration Samples 1.Concentrations of iron-thiocyanate complex formed in calibration samples: Hint: Since [Feଷା]>>[SCNି]in the calibration samples, you can assume that all the SCNିadded is converted to product. Calibration Sample # Concentration 𝑖𝑓 [FeSCNଶା]Concentration 𝑖𝑓 ൣFe(SCN)1 2 3 4 5 6 7 8 9 10 a)Show a sample concentration calculation for [FeSCNଶା]b)Show a sample concentration calculation for ൣFe(SCN)2.Prepare a calibration curve graph of absorbance vs. concentration for each of the iron-thiocyanate complexes. a)Attach the calibration curve graph for [FeSCNଶା]to these sheets. a)Attach the calibration curve graph for ൣFe(SCN)to these sheets. Note: When plotting the absorbance vs. concentration of the iron-thiocyanate complex formed, you should obtain a straight line with its intercept at the origin. : :
