During class, we performed a practical of determining a colourimetry curve for the reaction between Iron (iii) with thiocyanate. We used a colourimeter to calculate absorbance values and then plugged it into to excel to graph the calibration curve.
Then for the second part, we had slightly different concentrations and more diluted chemicals to reach equilibrium and what not. But from that data we recorded, we had to calculate the Keq value for each sample we collected. I'm not sure if my calculations are correct, so if anyone has time to look over them, could you please give me a heads up if I've done something wrong. It would be really appreciated.
