of sulfur dioxide and iodine in the presence of a buffer that reacts with hydrogen ions.
It means one mole iodine react with one mole of water

Answer / prasanna
The I2 in KF reagent reacts with water molecule and converts into hydroiodic salt. When water molecules are not available then the excess molecule of I2 will be detected by Iodine electrode. using the vol of KF consumed we can calculate water% in our sample.

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?
