What provides surface for the vapors to cool and condense in a fractionating column?
What is a fractionating column ? How does it help in the separation of miscible liquids ? Give one example.
Fractionating column is the most important part of the fractional distillation apparatus. This column is provided with some glass beads in it. Separation of miscible liquids by fractional distillation It helps to obstruct the upward movement of the vapours of the two liquids.
What provides surface for the vapors to cool and condense in a fractionating column?
A form of partition, adsorption, ion exchange, or affinity chromatography in which one phase is liquid (aqueous) flowing down a column packed with the second phase, a solid is called _______.
In column chromatography, the moving phase is?
The $$R_{f}$$ value of A and B in a mixture determined by TLC in a solvent are $$0.65$$ and $$0.42$$ respectively. If the mixture is separated by column chromatography using the same solvent mixture as a mobile phase, which of the two compounds, A or B will elute first? Explain.
Define the term 'elution' as applied to column chromatography.
Without using column chromatography, how will you separate a mixture of camphor and benzoic acid?
Fill in the blanks : In column chromatography ................. constitutes the stationary phase and the ........... as the molecule phase.
Fill in the blanks : In column chromatography, the .......... absorbed component will elute with the more .......... solvent.
Separation of organic compounds by column chromatography is due to:
