I was wondering what makes a substance soluble in polar solvent and insoluble in a nonpolar.

I know this is extreme noob stuff but if anyone has the patience i would greatly appreciate it.

it all has to do with how the chemical you are dealing is arranged, atomicly

boiled down to basics, a molecule is layed out in a certain pattern. that pattern can be either equally distributed with + and -, making a non polar substance, or it can be distributed unequally, making one side more + than the other, giving it a pole.

when trying to seperate substance A, which is comprised of both nonpolar(NP) and polar(P) substances, you use the attraction of P to P and NP to NP to obtain a more pure product. If the stuff you want is P, you use an NP solvent to first get rid of all the NP molecules, then take what didnt dissolve into that, and put it into a P solvent, where the P substance will dissolve into the P solvent, leaving any extra NP things that didnt get taken out by the first cleaning

someone else care to take it from here?

Next time google "chemical solubility".
