Question

graduated cylinders are not as precisely calibrated as are burets or volumetric pipets. briefly explain why it is acceptable to measure KI and HCl solutions in the titration with graduated cylinders rather than with pipets or burets.

Answer 1

I agree with what you've said but without knowing the particulars of the experiment I can't help you. Are you titrating I2 with thiosulfate? If so you measured the KIO3 precisely. The KI is an excess reagent and the amount of the excess is not that important and the HCl is just to make it acid; the precise acidity is not required. Clarify the post if I haven't guessed right.
