K-F meter

I. Principle: This instrument is used for determining water content by the Kart Fischer volumetric titration method, with the \"stop-time method\" employed to determine the endpoint. According to the half-cell reaction: I2 + 2e− → 2I⁻, when both I2 and I⁻ are present in the solution, the aforementioned reaction takes place at each of the two electrodes; that is, I2 is reduced at one electrode while I⁻ is oxidized at the other electrode, which results in an electric current flowing between the two electrodes. If there is only Iˉ in the solution and no I2, then no current flows between the electrodes. At the end of titration, trace amounts of Karl Fischer reagent are present in the solution; that is, both I⁻ and I₂ are present. At this point the solution conducts electricity, and the instrument indicates that the titration has reached its endpoint. Reaction equation: I2 + SO2 + 3C5H5N + CH3OH + H2O → 2C4H5N.HI + C5H5N.HSO4CH3. The water content in the sample is determined based on the amount of Karl Fischer reagent consumed in the titration reaction. It is clear from the principle that this method is not universal; therefore, it is not possible to determine the chlorine content along with the water content

I agree with Old Ox’s view; KF reagent contains sulfur dioxide, which reacts with the bases in the sample

Can methanol be used to absorb the moisture in chlorine gas, and then the moisture content in methanol be measured, thereby determining the moisture content in chlorine gas? So what can K-F be used to measure in chlor-alkali production?
