In Part A, how does the intenstiy of the color of the solutions vary with the concentration of FeSCN 2+ in solution? as the [FeSCN 2+ ] decreases, the solution becomes more red as the [FeSCN 2+ ] increases, the solution becomes more red the color of the solutions do not vary with the [FeSCN 2+ ] the [FeSCN 2+ ] is the same for all the solutions so the intensity of the color doesn't change cannot tell from the information given
