IntroductionThis is just one of the simple ways of identifying unknown compounds and separate mixtures. It is a separation technique that works based on the compound interactions as those compounds tend to move within a supporting medium. The compounds interact in two phases which are the mobile and stationary phase. The technique helps in analyzing, identifying, purifying and quantifying unknown separable mixtures. The mobile phase is either a liquid or gas which moves the solvent through the stationary phase during the process.

The stationary phase is a lab report chromatography or solid component that is fixed in a place for the procedure.Paper chromatography works majorly on capillary attractions. The capillary attraction which depends on adhesive and cohesive forces allows the mobile phase to move up the stationary phase due lab report chromatography created surface tension interaction from the forces. The major types are t3. lab report chromatography Materials and constituents page 5The purpose of this lab report is to explain what exactly happened to the labs, the time that the experiment was executed and apply the results and conclusions that were deduced.

Also, specify the errors that might have happened during the execution of the experiment.In the following experiment lab report chromatography going to be proved that a paper can separate a mixture of colours and that every colour reacts with a different way lab report chromatography put onto the paper strip.Chromatography is the name given to a method, which is very widely used for the separation of mixtures of chemicals and biochemicals, that depends on how fast a substance moves in a stream of gas or liquid past a stationary material to which the substance may be slightly attracted.Chromatography serves mainly as a tool for the examination and separation of mixtures of chemical substances.

Chromatography is using a fPaperChromatographyIntroductionThe purpose of this experiment is to observe howchromatography can repoort used to separate mixtures of chemical substances.Chromatography serves mainly as a tool for the examination and separation ofmixtures of chemical substances. Chromatography is using a flow of solvent orgas to cause the components of a mixture to migrate differently chromatogrpahy a narrowstarting point in a specific medium, in the case of this experiment, filterpaper. Chromatotraphy is used for the purification and isolation of various substances.

Achromatographically pure substance is the result of the separation. Becausepurification of substances is required to determine their properties,chromatography is an indispensable tool in the sciences concerned with chemicalsubstances and their reactions.Chromatography is also used to compare and describechemical substances. The chromatographic sequence of sorbed subPurposeThe purpose of the experiment is to determine the specific types of pigments found in a beat leaf and in a spinach leaf by using paper chromatography and two solvents: water soluble solvent and lipid soluble solvent.HypothesisIf a water soluble solvent is present, chromatograpny there will be the movement of only the water soluble pigments up the chromatography paper.

Through capillary action these pigments will travel up the paper until the bonds between the water and pigment become so weak that the pigment must break the attraction and leave itself imprinted at a certain height up the paper. Lab 1 lab report chromatography Thin Layer Chromatography Objective In this laboratory you will separate spinach pigments using thin layer chromatography chroomatography. Introduction Mixtures of compounds are very common in Organic Chemistry.

Most reactions produce more than one product. Naturally occurring materials are only rarely 100% pure. It is therefore desirable to have a simple, fast and chromatograpuy way to determine the purity of Organic mixtures. The separation of a mixture by passing it, in solution, over an adsorbent (such as Alumina or Silica Gel) is lab report chromatography basic idea of Chromatography. Chromatography is chromatogrqphy very general phenomenon.

It involves the passage of a mobile phase across a stationary phase in a column. Usually a mixture of compounds is present in lab report chromatography mobile phase. As soon as the mixture comes in contact with the stationary phase, some or all of the components of the mixture are adsorbed on it. As additionChromatography labPurpose: To separate food colorings into their component dyes using paper chromatography. Materials: Chromatography paper, Food coloring, Ruler, Pencil, Solvent solution, Test tubes, Test tube rack.
