What is the method of separating dyes?
chromatography
What is the name of the method used to separate dyes?
Chromatography is the method used to separate a mixture of dyes or inks.
What type of dissolved substanced is chromatogrsphy useful im separating?
A dissolved substance that has different solubility in a given solvent. They are useful in the separation of the dyes and food color.
Which dyes adhere best to chromatography paper?
ethanol
Is chromatography physical change?
Chromatography is a physical change because even though you are separating colors the original atomic identity of the colored ink being separated is still retained showing that a chemical reaction has not taken place.
What is the method of separating dyes?
chromatography
What is the name of the separation technique that allows us to examine the dyes used in food?
chromatography :)
What technique is used to separate different substances that are dissolved in a solution eg different dyes in paint?
chromatography
How could the different coloured dyes in green food colouring be separated?
You can use the technique called chromatography.
What is the chemical name for celluloid?
Celluloid is not a compound but a mixture of nitrocellulose, camphor, ethanol, stabilizers, dyes.
Is paint a compound?
All dyes are chemical compounds or mixtures of compounds.

what are the 4 ways of separating mixtures?
5 ways to separate mixtures are distillation, filtration, condensation/distillation, Evaporation, chromatography, centrifuging and magnetism.Chromatography - To separate different coloured dyes. The dyes travel up the chromatography paper at different distances before they cannot remain in solution. The more soluble dyes move further up than the less soluble ones, hence separating from each other.Distillation - to separate and collect a liquid from a solution of a soluble solid. The solution is heated in a flask until the liquid boils. The vapour produced passes into the condenser where it is cooled and condenses to a liquid. The pure liquid (distillate) is collected in a beaker.Evaporation - This method is suitable to separate a soluble solid from a liquid. If the solution is heated, the liquid evaporates leaving the solid behind.Fractional Distillation - This is a special type of distillation used to separate a mixture of liquids. Different liquids boil at different temperatures. When heated, they boil off and condense at different times. The apparatus features a fractionating column, which ensures that only the liquid boils at its boiling point will pass into the condenser.Filtration - To separate an insoluble solid from a liquid. The solid remains in the filter paper and the liquid goes through the paper into the beaker.Some of the example mixtures that can be separated using the above mentioned techniques:(1) separating dyes in inks, or chlorophyll in plants (ethanol as solvent) - chromatography;(2) separating sand from water - filtration;(3) separating ethanol and water - fractional distillation;(4) separating water from ink - simple distillation;(5) separating salt from water - evaporation

What is the name given to a dye or mixture of dyes that tell us if something is acid or alkali?
An indicator, for example Litmus.
What can be accomplished with paper chromatography?
Dyes and inks are used to color things we use (eg. colors for food, clothes and pens) The point of chromatography is to find out if the color in a felt pen is pure or a mixture of dyes.
