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

This lab is an opportunity to observe‚ study‚ and learn about ecosystems and how the environment sustains life but in a much simpler and smaller scale which is called Eco Columns. The environmental conditions in the Eco Column could sustain life for several weeks‚ therefore over the course of the several weeks we will observe and study the interconnections between each ecosystems. A self sustaining requires components such as energy flow and chemical cycle. This experiment will evaluate our knowledge

How To Obey One’s Father‚ While Being True To Love and Oneself By: Ophelia Posted: 11/2/2013 12:58pm EST When do we know when to listen to ones heart‚ but at the same time make the right choices by listening to others voices? Do we listen to the demands of our guardians? or is love what drives us to make better choices? Some of us are blinded by love‚ and I for one have experienced the treachery of being bashed by my own lover. I did not see what should have been sawn‚ because I was in the meadows

Lab 5 Column Chromatography: Isolation of Lycopene from Tomato Paste Reading: Zubrick‚ pages 79-82‚ 127-130‚ 138-139‚ 141-143‚ and 235-240 Pre-lab: look up the structure of lycopene. Introduction: Lycopene is the red pigment in ripe tomatoes and‚ as an antioxidant‚ helps to fight certain cancers. In this lab you will isolate lycopene from tomato paste. To do this you will first extract carotenoid pigments from the paste and then use column chromatography to isolate the lycopene from

Organic Lab 1: Fractional Distillation Discussion: With the purpose of the experiment being to identify the 30 mL of unknown liquid‚ the theoretical basis of simple and fractional distillation must be deconstructed and applied to the data obtained describing the liquid in question. Simple distillation is a separation technique which can be used to separate and purify distillates from a liquid mixture which ideally contains one volatile and one non-volatile compound. If such ideal conditions are

Compare the bone markings of the vertebrae and distinguish the differences between the cervical‚ thoracic‚ and lumbar vertebrae. The vertebrae are the irregular bones that create the spinal column. These irregular bones are divided into four sections which are the cervical‚ thoracic‚ lumbar‚ and sacral or pelvic spine sections‚ which are also referred to as curvatures. There are seven vertebrae that make up the cervical spine (neck); twelve vertebrae that make up the thoracic spine (chest); five

Post Lab #4- Column Chromatography Organic Chem 3418-2 March 3‚ 2011 Theoretical Background- The fluorene and fluorenone mixture was separated by first dissolving the mixture in heptane. Since “like dissolves like”‚ fluorene dissolves with the non-polar heptane and the polar fluorenone dissolves in the polar ethyl acetate solvent. This phenomenon was illustrated in class before the experiment‚ when it was pointed out why water will not dissolve fluorene‚ fluorenone‚ or transstilbene
