Question
Chapter 3.2, Problem 24E
Interpretation Introduction
Interpretation:Less purity of second crop of crystals than first crop should be explained.
Concept introduction:Filtration is procedure that is used to remove insoluble impurities, decolorized activated carbon from solution and also for purification of compound. Liquid that has been passed through filter apparatus is called filtrate while solid that cannot pass through filter is known as residue.

Select all of the options below that are used to increase
the purity in the purification of crystals.
Stirring the solution after mixing.
Filtering the crystals
Recrystallization at least once.
Slow cooling during crystallization.
Heating the pure crystals
Fast cooling during crystallization.
Which of the following statements is true when considering temperature during a recrystallization?
More than one answer may be correct.
Using ice to cool the sample will speed up the crystallization process so that large crystals will be formed.
It is important that the sample is dissolved in just enough hot solvent.
O Ideally the hot solvent used will keep the impurities dissolved OR not dissolve them at all.
Enough cold solvent should be added to dissolve the sample BEFORE heating it past its boiling point.
We separated a mixture of sodium carbonate and calcium chloride using Gravity Filtration. Additionally, did vacuum filtration for crystallized Vannilin. However we were not able to recover 100% of the original sample the question is: what do you think are the factors that contribute to low percentage recovery?
