Unformatted text preview: when it turned clear. 2) In the titration procedure part I the instructions tell you to rinse off the stirring rod used to break up the crystals. How would your results be affected if you did not do this? In part 2 adding KI too soon might result in the loss of I 2 by evaporation. How would this affect your answer? Well if I don’t rinse off the stirring rod, then the mass of the KIO3 decreases because it’s a waste of crystals, so then when the KIO3 decreases, the millimoles of KIO3 decreases which means a change in oxidation. If I add KI too soon, then the iodine will be lost because it will be vaporized and therefore the amount of thiosulfate would increase because then you would be titrating it more so for no reason, waiting for the reaction to happen....
