loss on drying we applied vaccum for some compounds and
some compounds are at 105c why
Answer Posted / falguni
As per
PV=NRT, if we decrease pressure, temperature also decrease.
Vacuum i.e. no pressure. If we heat our sample which has
low melting point(near 60C), it melts at 60C. Vacuum lowers
the temprature but effect on sample is in equilibrum to the
higher temperature. It does not melt the sample but remove
volatile solvents and adsorbed water.
