Answer / mallesh
The titrimetric determination of water is based upon the quantitative reaction of water with an anhydrous solution
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.

In HPLC Chromatographic separation Resolution equation is Rs = 1.18 (tR2 –tR1)/wh1+Wh2, Where, tR2 and tR1 is run time of eluent ratios of the distances from the point of application to the centers of the spots and the distance travelled by the solvent front from the point of application (retardation factor), and Wh1and Wh2 , is peak width of at half height. What is 1.18 ?
why required specificity in valdation
when we talk about change in entropy we consider total entropy means of surround +entropy of system but when we talk about change in Gibss free energy we consider entropy of system.explain with reason.
why using factor 1.00639 in burette calibration of kf
In BP2013, Loperamid HCl monograph. Assay by titration with 0.1N sodium hydroxide using hydrocloric acid 0.01N and reading the volume added between the 2 points of inflexion. I have a question that if the diluent solvent is ethanol is certainly consumed a amount of volume of titrant, so this volume must be eliminated on the result calculation or not apart from first point which is subtracted above.
