I am doing a lab on the determination of the equilibrium constant for the formation of Fe(SCN)+2. We used a spectrometer to measure the absorption of solutions with a varying initial concentration of Fe+3, but constant concentrations of SCN-. The reaction equation of Fe+3 + SCN- —> Fe(SCN)+2. Along with the SCN- and Fe+3 stock solutions, we also combined them with .3 M HNO3. We then calculated an average molar absorptivity and the equilibrium concentration of Fe(SCN)+2. From that concentration...
