Answer / ramu
Disodium tartarate is very soluble in methanol and gives
very accurate results.Dst molicular formula is
C4H4Na2O6.2H2O.
This molicular weight is 230.06.
Water content of DST is 15.66.
Calculation:In DST two water molicules are there=2*18=36
=(36/230.06*100)

Answer / v.r.sankara rao
Disodium tartarate is very soluble in methanol and it was a
primary standrad it have only two water moleule andgives
very accurate results.
Dst molicular formula is C4H4Na2O6.2H2O.
This molicular weight is 230.06.
Water content of DST is 15.66.

Answer / ramkrishna thakare
Disodium Tartarate dehydrate - is easily soluble in MEOH &
its water content ( moisture ) is known & constant. due to
2H20 Molecule we take constant 15.66 factor.

Answer / ravi
In DST there are two water molecues. Those two are very
stable.Eventhough we are drying upto 105c the molecule is
stable.when DST reacts with another substance these two
water molecules are stable.DST is soluble in methanol.

Water content value and LOD value is same in DST(15.66%)
and it is crystal structure captures precise amount of water.
water standard is better standard than DST in KF standarisation.
