Chromatography is the separation of compounds to allow us to see the different colours of that compound‚ for instance we may use chromatography in a school lab to see the real colour compounds of plants and grass‚ by using chemicals such as acetone we it will allow the object to break compounds and thus we can see the true colour of the grass. In today’s society there are many real world applications which use the chromatography technique in their line of work‚ an example of one of these applications

Encyclopædia Britannica Paper chromatography is used to separate "dissolved chemical substances". An example of dissolved chemical substances could be the pigments that make up a specific color‚ for example in a marker. When a chromatography paper experiment is done on a black marker‚ the experiment tends to separate all the different pigments that make up the color. In this experiment‚ the substance investigated was a black water soluble Giotto marker pen. Paper chromatography has two phases‚ the

Stem and Leaf Plots Examples 1. A stem and leaf plot is a method used to organize statistical data. The greatest common place value of the data is used to form the stem. The next greatest common place value is used to form the leaves. 17 stem leaf 2. EXAMPLE: Make a stem and leaf plot of the algebra test scores given below.

exchange Chromatography Ion exchange chromatography is a process for separating proteins and other molecules in a solution based on differences in net charge. Ion Exchange Chromatography relies on charge-charge interactions between the proteins in your sample and the charges immobilized on the resin of your choice. Ion exchange chromatography can be subdivided into cation exchange chromatography‚ in which positively charged ions bind to a negatively charged resin; and anion exchange chromatography‚ in

Chromatography Experiment of the Drosophila Eye Pigmentation Pathway Introduction: How can the use of chromatography help explain single gene mutations of the drosophila melanogaster bio-synthetic pigment pathway? This experiment was meant to help connect the mode of inheritance with different eye color mutations and pinpoint where they occur in the pigment pathway. The drosophila eye color is a result of two bio-synthetic eye color pathways‚ this is expressed as a trait or phenotype‚ a multigene

Transpiration and Leaf Resistance By: Bernina Berber Introduction Transpiration is a part of the water cycle process‚ and it is the loss of water vapor from parts of the plants. It is a process similar to evaporation. Evaporation and diffusion cause the plant tissue to have negative water potential. If you were to compare transpiration it would be like saying it is close to sweating (but in plants)‚ especially in leaves but also in stems‚ flowers and roots. Stomata are dots with openings on

Gabriel Alizaidy Liquid Chromatography September 14‚ 2009 Objective: To separate the components of unsweetened‚ grape flavored Kool-Aid. Procedure: Using two syringes‚ inject different concentrations of alcohol to extract red and blue dyes‚ and artificial flavoring. Data: Conclusion: Different dyes are shown when separated by different concentrations of isopropyl alcohol. Discussion of Theory: Chromatography‚ resolution and selectivity played major roles in making the experiment work

I picked my own story for The American writer O. Henry The Name of story is: The Last Leaf a brief summary of the story: The short story took place in New York City where two friends - Sue and Johnsy - live‚ work in art in a poor apartment‚ and publish their drawings in magazines‚ and thereby earning their living‚ and like any other artist‚ they hope to draw a masterpiece one day. One day‚ Johnsy fell prey to pneumonia. The doctor visited her and told her friend-Sue- that Johnsy could be cured

Chromatography lab Purpose: 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. Safety precaution: wear aprons‚ to make sure that you don’t get any of the alcohol on your clothes‚ and if you break a test tube you don’t get glass on you. Procedure: See-attached handout. Results: See chromatography with Audrey’s lab report.
