Compare and contrast Column (solid-liquid) chromatography, Paper Chromatography, and thin layer chromatography in respect to the size of the sample that can be separated, the ease of use, and the versatility of the method.

Expert Solution

ADSORPTION CHROMATOGRAPHY:

1) COLUMN CHROMATOGRAPHY : large scale seperations , mobile phase : liquid , stationary phase : solid

quantity of the sample needed is high because the sample has to be place in a column for seperations.

2) THIN LAYER CHROMATOGRAPHY : qualitative analysis (identification of organic compounds ) ,

mobile phase : liquid , stationary phase : solid (silica gel and alumina ) quantity of the sample needed is small because the sample has to be placed on a layer of adsorbent .

gives better result as compre to paper chromatography bands form are sharper

PARTITION CHROMATOGRAPHY :

1)PAPER CHROMATOGRAPHY : qualitative and quantitative (polar organic compounds and inorganic compounds )

mobile phase : liquid , stationary phase : liquid

quantity of the sample needed is small because the sample has to be placed on a thin layer of chromatogram

With respect to liquid column chromatography in which the stationary phase is silica, propose a suitable strategy for separating two components of a binary mixture that fail to move when hexane is the mobile phase and move the same distance when methanol is the mobile phase. Explain your reasoning.

A solid was dissolved in water and analyzed using thin layer chromatography. All the necessary precautions were taken to get a good result. The chromatogram had three spots with Rf values of 0.25, 0.38, 0.74 in the column for the solid. If a fresh sample of the solid were tested to measure the melting point, would the melting point have been sharp or have been a broad range? Explain your answer.

Thin Layer Chromatography utilizes a glass or metal plate coated with a thin layer of absorbent material such as silica gel. The sample is prepared similiarto paper chromatography and a solvent is used to elute the sample. 1. Which is the stationary phase? Plate Silica Gel Solvent 2. Which is the mobile phase? Plate Silica Gel Solvent 3. Which component is inert? Plate Silica Gel Solvent
