Does the crude unknown have to be dried in a desiccator before the recrystallization?

No, if you have time to proceed with the recrystallization on the day you evaporate, go ahead. (Be aware that part of the weight of crude unknown you measure is water. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
