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.
What is the method of separating dyes?
chromatography
What method is used for separating curcumin from turmeric?
Curcumin is separated by solvent extraction.
How do you obtain a pure solvent from a solution by distillation?
By separating the mixture of solute and solvent based on their boiling points.
Would water be a suiable solvent for every dye?
-Cationic dyes (basic dyes) are soluble in polar solvents such as water, alcohols -Nonionic Fat-soluble dyes line metal-free azo and anthraquinone dyes are soluble in aromatic and aliphatic hydrocarbons. -Metal-complex dyes are normally soluble in alcohols, ketones, glycoethers

How does chromotograhy work using particles?
Chromatography is a way of separating solutions. In schools dyes are usually used to illustrate this. Most dyes are actually solutions of different coloured chemicals. The colours are the solute particles. They are attracted by the solvent particles and the chromotography paper. Each solute is attracted by a different amount. When the colour is separated by chromotography the solutes which are held strongest by the solvent travel the furthest whereas the solutes that are held the strongest by the paper travel the least.
What solvent do you use to seprate dyes in ink?
alchole
What is the principle used in separation of mixtures?
separating an insoluble solid from a liquid: decantation, filtration separating a dissolved solid (solute) from a solution: evaporation, crystallization separating the solute and solvent from a solution: simple distillation separating a mixture of two miscible liquids: fractional distillation
How do you obtain a pure solvent from a solution by distillation?
By separating the mixture of solute and solvent based on their boiling points.
What is the term for separating a substance from contact with others as an island?
The Solvent
Why must the solvent level be below the colored spots in chromatography?
If the colored spot is below the level of the solvent, the spot will simply dissolve into the solvent.Chromatography works because the solvent climbs up the 'column' by capillary action, picking up the colored spots along the way and dragging them along. Because of the chemistry of the colors and the solvents, some of the colors in the spots are easier to drag along the column than others, and move along faster.
What is HCl compound used for?
