What solvents are used for recrystallization?

Answer 1

Water, methanol, ethanol, diethyl ether.........

....chloroform, methylene chloride, hexanes, heptane.....

How do you know which solvent to use? How else but by experiment?

AS a tip, for MOST organic substances, the best solvent to use is ethyl alcohol. Most organic solutes have some solubility in HOT ethanol, and as the solution cools, the solutes crystallize out... Ethyl alcohol has a good temperature range and can be placed in a sparkless freezer, is cheap, and as a bonus it smells nice...

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
