retention on paper chromatography Design and carry out a scientific investigation on any one factor that affects retention on paper chromatography CHEMISTRY LAB REPORT CHEMISTRY LAB REPORT Name: Sri Danielle Class: 9A Teacher: Sir Ajay Name: Sri Danielle Class: 9A Teacher: Sir Ajay Aim My aim for this experiment is to find out how different types of solvent will affect the retention factor in paper chromatography. Hypothesis I think that there will be a high RF value in paper chromatography

When people hear candy chromatography‚ they don’t know what to think about it. They of course know that it had something to do with candy. But just don’t know what. Candy chromatography is fun and simple. Candy Chromatography is a fun project‚ plus it has to do with candy. Candy Chromatography is an experiment to find out the true colors of the dyes in candy. When you put a skittle or an M&M in your hand in hot weather‚ the candy tends to bleed the color. And sometimes it shows more than one color

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.

their mouths and a happy‚ satisfied grin on their faces. The reason for conducting the research is to know how the colors of our favorite candy-coated sugary rewards came to be and that method of knowing is what we call “Candy Crhomatography”. Chromatography by definition according to Webster’s dictionary means “ a method for separating the constituents of a solution (gas or liquid) by exploiting the different bonding properties of different molecules”. In this case‚ the molecules being broken down

Thin Layer Chromatography Submitted in partial fulfillment of the requirements for: CHE 324 Organic Chemistry Laboratory Dr. Robert Duncan Fall Semester 2012 Caitlin Inman‚ Team Leader October 9‚ 2012 Tyler Byrd‚ Data Collection Shared Role‚ Technique Expert Introduction: “Chromatography is used to separate components of a mixture. For example‚ imagine a mixture of wood pieces‚ pebbles‚ and large rocks to be separated and the chromatography setup as a stream. Flowing water

Background Information and Research Paper chromatography uses selective adsorption on a strip of paper. It is used for separating and identifying mixtures that are or can be colored‚ especially pigments. This can also be used in secondary or primary colors in ink experiments. Is it used for Contaminants in rainwater‚ Analysis of narcotics‚ and Detection of substances in urine. Purpose • The purpose of this lab is to see the separation of dye on the candy.

Experiment 5 Title : Thin Layer Chromatography Objectives: i. To distinguish polar and non-polar solvents. ii. To familiar with the analysis technique by using the thin layer chromatography. iii. To differentiate the retention factor‚ Rf for different compounds. [pic] Result: |Compound |Distance traveled by the compound | |o-nitroanaline |2.45

It was concluded that the product created was paracetamol when a thin layer chromatography test was performed and observed under ultraviolet light (which is discussed further down the page). An unknown substance was treated with acetic anhydrate and resulted with paracetamol. A compound that behaves in this matter is 4-aminophenol and is widespread in the industrial production of this drug. Upon these observations was the build up of “Chemical A” decided. When 4-aminophenol is t treated with

Chromatography of Commercial Analgesics Using the thin layer chromatography the major components of a commercial analgesic tablet will be indentified and purified. The active ingredients of the analgesic used were characterized by comparison with chromatograms of aspirin‚ acetaminophen‚ ibuprofen‚ mefanemic acid‚ and caffeine through the use of UV chromatography then the Rf value was calculated for each solvent. INTRODUCTION In this experiment‚ thin-layer chromatography (TLC) will be used

CHEM 3152-003 Experiment 2: Fractional Distillation and Gas Chromatography Introduction: The purpose of this experiment was to separate a mixture of ethyl acetate (EtOAc) and toluene by using the method of fractional distillation and to analyze the fractions using gas chromatography (GC). ethyl acetate toluene Distillation is a method known as separating or purifying a liquid or mixture by vaporization and condensation. In a simple distillation‚ the liquids being separated boil below 150 0C
