Question
Label the following statements with a T for true, and an F for false. When determining a melting point for a purified compound, a melting point range of 10 degrees Celsius is an indication of a good purification. The mother liquor of a Recrystallization is saturated with the compound of interest and contains the soluble impurities. During distillation, the temperature of the distillation should be above the boiling point of the solvent to be sure all product carries over. During a Recrystallization, the compound to purify should be very soluble in the hot solvent, but have limited solubility in the solvent when cold.Explanation / Answer
a)
False, it is too big, it should be +/- 2 °C
b)
Most likely true, since it had metling point range
c)
True, if T > Tboil, we can get 100% or nearest purity
d)
True, since high T will make more soluble compounds
