Experiment 34: An Equilibrium ConstantKaitlyn ChomkoTiernan Noll and Saajan VemalaChem 1310/DA8Professor Richard H. PerryBrandon02/23/18
Hypothesis: If the volumes and molar concentrations of NaSCN of Fe(NO3)3are varied between solutions containing HNO3the absorbance and transmittance between the solutions will be different. The more NaSCN in a solution, the lower the percent absorbance. A calibration curve of absorbance versus [FeNCS2+] can be used to determine the equilibrium molar concentration of[FeNCS2+]. From there, the equilibrium constant is calculated by using this equation:Kc=FeNCS2+¿¿Fe3+¿¿SCN−¿¿¿¿Materials and Methods:Source: Please refer to experiment 34: An Equilibrium Constant in Laboratory Manual forPrinciples of General Chemistry by J.A Beran on page 283There were no deviations in this experimentData: II Lab/excel ex- 34.xlsx
