Unformatted text preview: using the calibration curve found in part 1. Then using that we determined the equilibrium concentrations of Fe3+ and SCN- then found the equilibrium constant, K, for the solution. Possible sources of error may have arisen from having waited too long and the solution heating up, giving a false absorption value. Also having set up the spectrometer wrong could have given incorrect absorption values and thus thrown off the entire experiment. Balanced equation: Fe3+ + SCN- -> Fe(SCN)2+ Equilibrium constant: [Fe(SCN)2+]/([Fe3+][SCN-])...
