Question
20) What experimental technique we use to separate a m liquids? 21) Apart from silica gel, which othe preparative column chramatography? r compound can be used as a stationary phase is the stationary phase in preparative and thin layer chromatographs, mobile phase? Is it the solvent used for driving the compounds or the 22) If silica gel what is the compounds themselves? 23) What is the purpose of p utting sodium sulfate (Na2SO4) crystals in the organic layer isolated after extraction? Can we use a mixture of solvents for eluting compounds in TLC and Preparative Chromatography?Explanation / Answer
1. we use simple distillation and fractional distillation experimental technique for the separation of a mixture of high boiling liquids.
2. Apart from silica gel, alumina can also be used as a stationary phase for the preparative column chromatography.
3. solvent is the mobile phase in the preparative and thin layer chromatography. It is the solvent which drives the components on the stationary phase.
4. Sodium sulfate is a drying agent and is used to remove the water from the organic layer.
5. yes, a mixture of solvents can also be used for eluting the compounds in TLC and preparative column chromatography.
