what is difference between moisture contents and water contents ?

Answer Posted / haran

moiture content and water content are similar wards but
contently both separeted by prsence H2O in sample
moiture content : less than 1.0 % H2O in sample
for calculation KF-solution stadised by using DST (di
sodium tartate Dihydrate )
water content: sample with more than 1.0% of H2O for
calculation purpose KF-solution stadised by using pure water
(mill-pore water)
and always DST factor less then that water factor.for ex
DST kf factor was Around 5.0-5.2 and water kf factor was
around 5.1-5.3 (+or- 0.4)
