Answer Posted / geethanath
The KF solution contains Iodine. Which will liberate from the solution. So When Iodine is liberate from the solution the strength of the solution will dicrease. One molicule of iodine will react to one molecule of water. For determining the Iodine strength we have to standardise.
Calibration is a periodic review point to check whether the instrument is working properly or not.
KF factor shold not be equal 5 at every time. The molarity may differ for hygroscopic materils. The diluted KF is having 2.5 as a factor.
