Answer A5 is wrong
Dialysis and chromatography both can be used to separate different molecular species. Which of the following features is NOT an advantage of chromatography compared to dialysis? A. Chromatography can distinguish between very large molecules, whereas dialysis cannot. A. Chromatography can separate a sample into three or more fractions each with a different protein of interest, whereas dialysis separates a sample into only two fractions. A. Chromatography can be used to purify precipitated proteins, whereas dialysis cannot. A. Chromatography can be used to separate molecules on the basis of charge, whereas dialysis cannot. A. All of the above are valid advantages.Explanation / Answer
The false statement is
Chromatography can be used to purify precipitated proteins,where as dialysis cannot.
Therefore option A3 is correct.
