Answer / ashvini s. vartak
During titration Py.SO3 can react with water which varies
the stoichiometry of water & iodine from 1:1 to 2:1.To
prevent such side reaction methanol is added

Answer / ramesh yadav
because methanol is a protic solvent and proton is required
in kf reaction

Answer / sridhar bonam
According to KF principal is medium should be need lower alcohol or organic solvent and lower alcohol is methanol.
The iodine react with water , the consumed iodine value is water content.
Sample weight is calculated based on the stoichiometry value i.e (1:1 to 2:1)

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 ?
