What does this mean?c.What were the effects of adding/removing reactants to/from the equilibrium mixture? (Fe(NO3)3 and EDTA)B.Theoretical Approach
and recording a standard A470and then introducing heat, removing heat, and adding other solutions this principle was further tested.C.Observations and Resultsa.FeSCN2+is an orange-red color, and is not very viscous. It’s almost the color of the orange tootsie pops. At room temperature, the stock solution had an Abs. of 0.969 @ 468.54nm. b.Approximately 30mL of 0.0020 M Fe(NO
