Question

How would the accuracy of your determined K_eq change if all of your volume measurements were made with graduated cylinders rather than pipets? If all of the SCN^- was not converted completely to FeNCS^2+ when the calibration curve was prepared, would this raise or lower the value of K_eq? Explain. Use the mean value you determined for K_eq to calculate the SCN^- concentration in a solution whose initial Fe^3+ concentration was 4.00 Times 10^-2 M and initial SCN^- concentration was 1.00 Times 10^-3 M. Is all of the SCN^- in the form of FeNCS^2+?

Explanation / Answer

The accuracy of the determined Keq would decrease because when the capacity of a volumetric material (or measurement instrument), in chemistry experimentations very smalls volumes can make a huge difference, graduated cylinders posses a lower accuracy compare to a pipet and that accuracy is tranfer to the experimental results.
