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

Answer / shreya

kf determine all bond which were present in the sample weak
bond of hydrogen ion or as well as strong bond bt lod
determine weak bond of hydrogen.ion.......

Answer / prabhakar

In kf method we can detect only water % present in the drug bt in lod we can detect the water and as well as solvent present in the sample.sothier is different when we done lod and kf of sample of one material.

Answer / nagasrinu

if any metel hydrates is presents in our samples it is one
of possible reson for geting more moisture by kf

or

if the sample havig lums then possible to get more
moisture by kf beacuse sample is competly soulble in solvent

Answer / falguni patel

KF and LOD is different procedure..
KF determine binding or we can say absorbed and adsorbed water content where as LOD determine only adsorbed water content and some volatile solvent.

Answer / sandra nagarjuna

Case 1:KF will be more when samples contain lumps or big crystals
Case 2: If u r sample contain acetone or ketones ,in Kf method these two reacts with kf reagent and forms further water, so it will be more when compared to LOD

Answer / trinath devarakonda

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.
