What is the difference between STANDARDIZATION and CALIBRATION of instrument like KF? why do we standardization of KF everyday? Why the KF factor being only 5.02 etc?
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.

I have compare C2H2-air and C2H2-N2O flame AAS on determination calcium. Both use same range of std to plot calibration curve. (2-6ppm) When i measure the sample with phosphate, KCl and LaCl, C2H2-N2O flame give false positive result, around 0.5ppm. When i measure the sample with phosphste, KCl and EDTA. C2H2-N2O flame also give 0.5ppm false positive. But both above mentioned sample would not give false positive when measured by C2H2-air flame. What is the reason?
