1)how would the accuracy of your determined keq change if all your volume measurements were made with graduated cylinders rather than pipets ?

Question

2) 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 Keq? Explain.

Thank You So Much!!!!!

Answer 1

1) The accuracy of the determined Keq would be lower if all the volume measurements were made with graduated cylinders rather than pipets. This is because graduated cylinders are not as precise as pipets, and therefore the measurements would be less accurate.

2) If all of the SCN^- was not converted completely to FeNCS^2+ when the calibration curve was prepared, this would lower the value of Keq. This is because the calibration curve would not be as accurate, and therefore the Keq value would be lower than it should be.
