Essays on Chromatography

Abstract Pigments extracted from different greens have different polarities and may be different colors. Mixed pigments can be separated using chromatography paper. Chromatography paper is able to separate mixed pigments due to their polarity and solubility. Pigments of chlorophyll a, chlorophyll b and beta carotene will be separated on chromatography paper because each has its…

Ink Chromatography Lab Background Information Paper chromatography is an analytical method that is used for separating and identifying mixtures of substances into their smaller parts. Paper chromatography works because the ink used contains several dyes (pigments) that when place on porous paper are dissolved in a solvent by capillary action. When the pigments (solutes) are…

The chromatography lab is to understand how molecules with similar molecular properties can be separated with paper chromatography. These differences will be interpreted to see the distinction of separate chemical substances. Pre Lab Questions 1. Explain capillary action as it pertains to water and paper. Capillary action makes water draw up the paper. As paper…

In extremist halogenations lab 1-chlorobutane and 5 % Na hypochlorite solution was assorted in a vial and put through trials to give a merchandise that can so be analyzed utilizing gas chromatography. This experiment was performed to demo how a extremist hydrogenation reaction works with methane seriess. Four isomers were attained and so comparative responsiveness…

Background Information and Research: 1. Paper chromatography type of method that is used to separate mixtures of substances from a solution. 2. There are many uses for paper chromatography, especially concerning the fields of chemistry and biology. One use is to allow scientists to detect any sort of contaminants is rainwater. Another use is to…

Abstract Paper Chromatography uses a chromatogram paper as its stationary phase and the solvent as the mobile phase. Retention factor is the ratio of the distance travelled by the sample to the distance travelled by the solvent. This experiment aims to separate organic compounds, to compute Rf values and to identify unknown compounds using Rf…

Using Chromatography to separate Kool-Aid solutions and visible spectroscopy to measure light passing through Date of Experiment: September 18, 2013 Abstract: Homogenous mixtures can come in the form of colored solutions, like the one used in our experiment, which was Kool-Aid. The fact that it’s a homogenous mixture means that it is thoroughly mixed. Chromatography…

Candy chromatography is a method of analysis of separating and comparing of dyes used in candies and food coloring. It is also a proven method to analyze candy and its complex mixture, without having to taste it. These complex mixtures can be separated back into pure substances. To find out the ingredients of a favorite…

Separating Ferrocene and Acetylferrocene by Adsorption Chromatography Dry Pack Method Leah Monroe February 27, 2003 Organic Chemistry Lab II Experiment performed on February 18 and 20, 2003 Abstract: Adsorption column chromatography is one way to separate compounds out of a mixture. In this technique, a solid stationary phase called the adsorbent is packed in a…
