Answer / n.senthilkumar
Sodium Tartrate Dihydrate is not absorb any moisture and
and more accurate we are going to select for DST when
water content sample <1.0 %only and DST when dissolved in
methanol not degrade

Answer / lukka gowrishankar
1.0 DST is not absorb any moisture from the atmosphere in the room temperature.
2.0 DST is primary standard.
3.0 DST Had known water molecule(2H2O) and had constant water content value 15.66%
4.0 DST is easily dissolved in methanol and not degraded in methanol.

Answer / kalyani
1.this if the primary standard.it has known water
molecules .it cannotabsorb any moisture.so water molecules
are constant.

Answer / hema latha
because it is primary std. it will not absorbs water
content from the sample at room temp.and it will give more
accurate results for the determination of the KF factor.
