The precipitation of NaX (X = Cl, Br, I) from their saturated aqueous solution by three miscible organic solvents (MOS)—acetone, acetonitrile and isopropylamine—was studied for various MOS-aqueous solution volumes ratios. It was found that the fraction precipitated f is given by where V is the volume ratio and K and Vcare constants. For the case of NaCl this plot was found to be a broken line composed of two straight lines intersecting at the point of “salting out.1’ A scheme is suggested to separate the three electrolytes using isopropylamine to precipitate NaCl and acetone to precipitate NaBr.
