Question

In the titration procedure, part 1 of the instructions tell you to rinse off the stirring rod to break up 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 i2 by evaporation. how would this affect your answers?

Answer 1

If the part 1 is not done correctly, the titration will take longer. If the ki is added too soon, the I2 will be unstable and partially titred and will evaporate.
