I was reading about washing non polar soluble chemicals with a polar solvent like water. How exactly is that done? If you add water to the non polar solvent containing the chemical to wash away all the water soluble chemicals how would you separate the water from the non polar? Would you have to evaporate the non polar solvent before adding the water? For example say I have a mixture of chemicals. Only one chemical is soluble in a non-polar solvent like acetone and thats the one I want to isolate. Would I have to evaporate the acetone and wait until the solid chemicals are completely dry before washing with water?
