When we get Moisture content by KF higher than by LOD, what does this indicate?


Answer #1
KF titration is the most accurate method in analysing
moisture content. But it is coastlier and maintaince is too
high. So in analysis of moisture content an alternative
experiment is Loss on Drying(LOD), which gives approximate
moisture value present in the given substance.

Answer #2
In some cases, bounded water molecule will not come out during drying(LOD). But in KF, the compound is completely dissolved in the medium in such cases moisture content by KF is higher than LOD.

Answer #3
it means that sample contents bounded water. only in this case moisture content can be more than Lod
