Answer / suresh palacharla

I think that the question was wrong,why i am saying is in
KF titration the reaction takes place between iodine and
water and methanol acts as Media only.

Answer / subash

In KF titration the reaction takes place between I2, SO2,
Methnol and H2O and base acts as a buffer inorder to keep
the pH of the solution between 5.5 and 8.0.

methnol+ SO2+base gives intermediate alkyl sulphite salt
which is then oxidized by I2to an alkyl sulphate salt. This
oxidation reaction consumes water.
