Is there a way to increase the solubility of ANY solution?
Yes: Henry’s Law
Solubility is proportional to pressure
S~P
S1/P1 = S2/P2
If sol. Is 1g/L at 1 atm, it will be 2 ______g/L at 2 atm Everyone: if solubility is 3.45 g/L at 5.6 atm, what is the solubility at 1 atm? 3.45/5.61 = S2/1
S2 = 0.614 g/L

5. Will heating or pressure help?
6. Make Crystals
How to make crystals:
Watch a video online here or play the flv file here or the avi file here
The process:
The principle:
recrystallization supersaturation
and cool
Or evaporate Or Reduce pressure
The process of forming the very first crystal during crystallization is called
nucleation
