What is separation in chromatography?
Chromatography is a physical method of separation in which the components to be separated are distributed between two phases, one of which is stationary (stationary phase) while the other (the mobile phase) moves in a definite direction. The effluent is the mobile phase leaving the column.
What type of mixture are separated by chromatography?
Paper chromatography is used to separate mixtures of soluble substances. These are often coloured substances such as food colourings, inks, dyes or plant pigments.
Is chromatography used to separate?
Chromatography is a process for separating components of a mixture. The different components of the mixture travel through the stationary phase at different speeds, causing them to separate from one another.
How does separation occur in chromatography?
Chromatography is a method of separating mixtures by using a moving solvent on filter paper. The solvent flows along the paper through the spots and on, carrying the substances from the spot. Each of these will, if the solvent mixture has been well chosen, move at a different rate from the others.
Is chromatography a physical process?
Chromatography – a physical method of separation that distributes components to separate between two phases, one stationary (stationary phase), the other (the mobile phase) moving in a definite direction.
Is chromatography homogeneous or heterogeneous?
All of the inks that are mixtures are homogeneous mixtures because they are consistent throughout- until you separated the colors using chromatography you could not tell that it was a mixture because the mixture was evenly distributed.
What is the solvent in chromatography?
A solvent in chromatography is the liquid the paper is placed in, and the solute is the ink which is being separated.
Does chromatography use physical or chemical properties to separate components?
Mixtures can be physically separated by using methods that use differences in physical properties to separate the components of the mixture, such as evaporation, distillation, filtration and chromatography.
Does chromatography use physical or chemical properties?

Which substances can be separated by distillation?
Distillation is used to separate liquids from nonvolatile solids, as in the separation of alcoholic liquors from fermented materials, or in the separation of two or more liquids having different boiling points, as in the separation of gasoline, kerosene, and lubricating oil from crude oil.
