please make more a level tutorials
You are genius
Sir please do videos on melting and boiling point determination for a level
you deserve a knighthood mate
y do u use a minimum amount of solvent
namZ ? Lmaoo i literally came here to get the answer and he never said why feels bad
i thought he did mention that the product wont crystallized if theres too much solvent used, no?
what is the difference between crystallization and recrystallization?
kim ho in recrystallisation youll be remaking the crystals u made in the first place
Except theyll be purer after all these steps in the video
