Iron(III) Thiocyanate Revisited: A Physical Chemistry Equilibrium Lab Incorporating Ionic Strength Effects
Cathy L. Cobb and G. A. Love
Augusta State University, Department of Chemistry and Physics, 2500 Walton Way, Augusta, GA 30904-2200

Abstract
A physical chemistry laboratory exercise is presented in which the thermodynamic equilibrium constant for Fe3+ + SCN- <--> Fe(SCN)2+ in 0.5 M acid is calculated from the experimentally observed equilibrium constant and activity coefficients generated by the Davies extension of the Debye-Hückel theory.
