Asked by Cheech

Water/methanol and water/acetone are viable solvent systems for recrystallization,but water/chloroform
and water/pentane are not. Briefly explain in 1-2 sentences.
Answered by DrBob222
water/chloroform are not miscible.
Did you mean pentanol. Water/pentane is liquid/gas.
Answered by Cheech
no its pentane
Answered by DrBob222
Frankly I don't see how a liquid/gas mixture would be of help in recrystallization of a solid.
Answered by DrBob222
Pentane boils at 35C or so; therefore, I suppose it is a liquid at room T but it isn't miscible with H2O.
