Unformatted text preview: adding KI too soon might result in the loss of I2 by evaporation. How would this affect your answers? Not rinsing off the stirring rod will allow for an easier contamination of the sample, resulting in different numbers for the amount of titrant required to reach the endpoint. Adding KI too soon would cause the I2 to evaporate, causing the number of milliters used to titrate the sample to be relatively low. 3. For all measurements provide an estimate of the uncertainty involved. Estimate the overall uncertainty of your results....
