Experiment 1: Recrystallization
Making a solid from a liquid
-
Solution to solid is a precipitate
-
Gas to solid
-
Ordered 3D array of atoms/molecules
Crystals are special kinds of solid because they have a repeating structure
-
Crystallization:
Separation is 80-85% pure
-
Purification is 95% or above
-
