GAS CHROMATOGRAPHY

State definition of Chromatography

• The process by which particles move from a region of higher concentration to lower concentration

• The process by which water is purified

• The method through which solutes are separated

When using water as a solvent which type of molecule is likely to have the highest R_f value

• Polar

• Non polar

Some mixtures can be separated using chromatography

• True

• False

In case of chromatography the solvent risen up due to

• Solute

• Filter paper

• Capillary action

• None of the above

The retention factor is used for

• to zero the chromatography scale

• to retain solvent

• to identify unknown compounds in a sample

• as a starting tool for chromatography

The substance in the mixture that has the greatest affinity for the stationary phase will travel

• Fastest

• Slowest

Chromatography separates the mixture of dyes on the basis of their

• density

• gravity

• solubility

• boiling point
