Chromatography separates a mixture of?
Chromatography separates a mixture of pigments, usually in inks. You can separate colours in food and felt tips. The different solubilities of the different ink pigments, make some rise above others so you can see them clearly.
What is paper chromatography?
Paper chromatography is a technique used to separate a mixture into its component molecules. The molecules migrate, or move up the paper, at different rates because of differences in solubility, molecular mass, and hydrogen bonding with the paper.
How is chromatography used in everyday life?
some applications are; "Separations of inks, amino acids" from a mixture , blood and urine anlysis, from a mixture
In chromatography how are the sunstances carried up the paper?
The solvent rises up the chromatography paper (blotting paper) by capillarity. When the solvent reaches the "spot" it dissolves the mixture of coloured chemicals. There is now a solution; this is a mixture of solutes dissolved in the solvent. The molecules of these different chemicals are all different sizes. The simple explanation is that the smallest solute molecules travel almost as quickly as the solvent molecules and so get carried to the top of the chromatogram. The largest solute molecules travel very slowly and stay near the bottom. So some of the coloured chemical travel further than others.

What are the process to separate mixture?
Filtration, evaporation, chromatography, and distillation are some physical processes to separate a mixture.
How does chromatography help to solve mystery's?
because it will separate the chemicals and give the investigators some evidence

Use of gas chromatography in pharmaceutical industry?
Chromatography is a laboratory process that occurs in several steps and is used to separate mixtures of various chemicals into their individual components. The governing principle of chromatography is that different chemicals in a mixture have different degrees of dissolving in a liquid or sticking to a solid surface. In other words, chromatography can identify a chemical and separate it from a dense mixture of other chemicals and show it on a surface. Various chemicals in a mixture have different sticking ability on a surface. By varying this process in many ways, the chromatography technique can be used to separate any amount of quantities ranging from micrograms (in laboratories) to tons (in chemical plants). There are various chromatography procedures that have become popular since the invention of chromatography by Russian botanist, Mikhail Semyonovich Tsvet, in 1901. In the chromatography processes, a stream of liquid, that is called mobile phase, is made to flow through a tube known as column, and it is packed with porous solid material, called the stationary phase. The sample of the mixture that is to be analyzed is sent through the mobile phase and as the mixture proceeds in the tube, the compounds are separated. Chromatography is preferred over many other techniques as it doesn't cause any molecular changes in the composition of the chemicals involved. Uses of Chromatography Chromatography has evolved to be one of the most widely used chemical techniques to separate particles and contaminates in chemical plants. For example, in the chemical industries, pesticides and insecticides like DDT in the groundwater and PCBs (Polychlorinated biphenyls) are removed by the process of chromatography. As a major testing tool, chromatography is used by government agencies to separate toxic materials from the drinking water and also to monitor air quality. Chromatography is used by pharmaceutical companies to prepare large amounts of pure materials that are further required in making medicines. Also, it is used to check the presence of any contamination in the manufactured compounds. In the field of organic chemistry and pharmacy, chiral compounds are very close to each other in terms of atomic or molecular weight, element composition, and the physical properties. However, they exist in two different forms, called the enantiomers and optical isomers. Both these compounds though may appear to be same, have very different chemical properties. So, in pharmacy, chromatography becomes crucial to analyze the exact chiral compound so that correct medicines can be manufactured. For instance, a compound called thalidomide has two optical isomers and one of the isomers can cause birth defect if a pregnant women consumes it in early stages of pregnancy. So, it is important to carefully separate the isomers. Chromatography is used as a technique to separate the additives, vitamins, preservatives, proteins and amino acids. Some other uses are in the detection of drugs or medications in the urine and the separation of traces of chemicals in the case of fire in houses or buildings. It is also very popular in forensic science for investigative purposes. Chromatography technology has gained immense industrial popularity in the past few decades as it can separate chemicals that just differ even in their atomic orientations in space.
What are four methods of separating the parts of a mechanical mixture?
A centrifuge might separate out a mixture if the particles that are mixed together are of significantly different sizes/densities, but other than that there aren't any good ways to mechanically separate out a mixture. The answer is filtration because filtrarion seperates the two things after filtrated.... (eg: water and bacteria are a mixture, but if you filtrate them, the 2 substances separate making them unmixtured.) ..... the answer again is filtrate.
Is pudding a mixture or solution?
Pudding is chemically complex; basically I would consider it to be a mixture, however, there are some chemicals which are dissolved in other chemicals in the mixture.
Name two processes that are used to seperate mixtures?
filtration and distillation are two common separation methods

What are some different methods for separating the parts of a mixture?
It really depends what the mixture consists of. You would not use the same method to separate sand from gravel as you would to separate salt water from pure water.Some common separation methods include:Filtration: works best for solids suspended in a liquid (to separate sandy water into dry sand and pure water for example) or for two solids with very different particle sizes (to separate a mixture of sand and gravel).Distillation: works to separate liquids that have different boiling points. This method is used to separate alcohol from water (to make hard liquor) and the essentially the same method is used to take oil from the ground and turn it into petroleum products such as gasoline. Chromatography: used to separate mixtures of liquids based on polarity. Many different types exist, including thin layer chromatography (TLC), gas chromatography (GC), and column chromatography. Extraction:used to separate a mixture of solids based on their solubilities in organic and inorganic phases. Differences in pH can also be used to separate different solids by selectively ionizing one compound, causing it to dissolve more readily in inorganic solution.See the Related Questions to the left for more information.
