Purpose 1. To prepare a dry-packed sample of product mixture of ferrocene and Acetylferrocene 2. To separate and purify the components in the product mixture by column chromatography. 3. To check the purity of the components by thin-layer chromatography (TLC). 4. To calculate the yield of acetylferrocene and the percent recovery of unreacted ferrocene.

The purpose of column chromatography is to separate one compound from another by the differing polarities in the compound. This technique is important in organic chemistry because certain experiments may require the separation of compounds in solution to be used for chemical synthesis and/or analysis of a particular desired product by isolating it. Fluorene is to be separated from 9-fluorenone using the technique of column chromatography. The success of separation and purity is determined with analyzation

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

mobile phase can be liquid‚ gas‚ or supercritical fluid. How Does Chromatography Work? Chromatography is a surface effect. It works by first starting off with an unidentified liquid being injected into a column. As the chemicals in the liquid move down the column‚ they separate depending on their physical and chemical attributes‚ such as speed and weight. To easily picture the process‚ the example will pertain to a paper chromatography process in which the liquid is moving over the paper‚ separating

Gas Chromatography: Purifying alcohol Introduction The goal of this lab is to understand the principles of chromatography by purifying alcohol using fractional distillation. Running standards with gas chromatography we were able to see and calibrate our data to find not only how much ethanol our alcohol attained but also what a mixed unknown sample contained. Chromatography is a way of being able to separate substances in solution that can help not only identify the analytes (the studied

Rock Candy By Paula Muniz OBSERVATION: I already know that to make rock candy you need water‚ sugar and a skewer and maybe a sugary syrup. Rock candy usually takes around 10 days to make for the candy to crystallize. I know that when making rock candy you can use different types of sugar‚ however granulated sugar is the most used. Sometimes I wonder whether or not you can taste a difference in the rock candy when it is made with a different sugar? I also know that the longest rock candy

cocaine and crystal meth. Rock candies are one of the many candies that people all over the world enjoy. Rock candies are created by using water and sugar with a process of heating and cooling. Pretty simple concept on how to create rock candy‚ but a lot more is involved with the chemical process and the history of rock candy. Sugar used to be used for medicine before the 18th century when people found out it tasted great aswell. For centuries Rock Candy has been recognized as having
