Briefly include a statement of purpose for this experiment, relevant conceptual background, and general equations. You must include discussion on [FeSCN2+]std­ and why its absorbance is so important in determining the [FeSCN2+] in the other equilibrium mixtures. Given that the solution is a dark red, also discuss why the reaction was measured using blue light (470 nm).
