1. Wher NaSCN solutions in this experiment, a student mistak FeNCS2 ion solution be higher, lower, or unafected enly used a graduated cylinder instead of volumetric therewere fingerprints on the auvette? Briefly explain pipets. After collecting all the data, the student realized he'd used the wrong piece of equipment, but he didnt redo the experiment.Also, he later reakzed that he had consistently misread the graduated cylinder and had thus transferred volumes that were actally 5% than the recorded volumes How would the error described in 2(1) affect FeNCS2 ion concentration in the solution? Incorporate these measurement errors into the cs data for one of your equilibrium solutions, and caloulated recompute K for that solution Determine whether the Brietly explain student's measurement errors would cause each of the following, as recaloulated by you, to be higher than, lower than, or identical to the value you originally deter mined. Briefly explain (2) (1) the caloulated SCN" ion concentration in the standard solution (3) How would the error described in 2(1) affect the calaulated K? Briefly explain (2) the slope of the Beer's Law plot 3. Briefly explain why you can make the assumption that all of the SCN ion in solutions S2-S6 has been converted to FeNCS2+ ion (3) the calculated equilibrium solution concentra- tions 4. Verify the assumption described in Question 3. To do so, use your mean Kg to calculate the equilibriunm SCN ion concentration in Solution S6. The initial Fe3 ion concentration should be 4.00 Ã 10-2M, the initial SCN" ion concentration is recorded on Data Sheet 1 You will have to solve a quadratic equation (4) calculated K
