ORGANIC CHEMISTRY LAB 2: Separation of Organic Liquid Mixtures Introduction: In this experiment‚ a mixture of two compounds‚ cyclohexane and toluene‚ was separated into fractions by the techniques of simple and fractional distillation. The individual fractions that were gathered from the distillation were analyzed using gas chromatography (GC) and used to compare the efficiencies of the two different distillation techniques. The ultimate goal of this experiment was to determine whether simple

The calculations for colligative properties do not depend on the identity of a substance that is being used because only the amount of the substance that is used plays a role. The types of calculations that are colligative properties are: freezing point of depression‚ boiling point elevation‚ vapor pressure lowering‚ and osmotic pressure.1 Colligative properties are present in everyday life‚ such as adding salt to a boiling pot of water. By adding salt to the water‚ the boiling point of elevation

Phoenix Organics is a company that’s goal is to make a difference to the community‚ to the planet and to the health of its people. Their vision was to create something that would be good for the planet and good for the health of its people. And so in 1987 Chris Morrison‚ Roger Harris and Deborah Cairns created the first Phoenix product. The company started with a drink called "Ginger Fizz"‚ a naturally fermented product that was often determined to get out of the bottle before the top was cracked

A detailed explanation‚ one paragraph or more in your own words‚ of the colligative property being discussed and why that property changes the way that it does when the amount of solute is increased. A detailed description‚ at least one paragraph‚ of a real-world application of the colligative property‚ including an explanation of how this application of the colligative property is important or useful to those affected. The real-world example must be one that was not mentioned in the lesson. An

The aim for this experiment is to investigate the effects of different storage environments on organic and non-organic bananas‚ to see which one lasts the longest over a period of time. The study was separated into 5 groups that were each labeled to a location in a standard family home that would‚ over time‚ begin to affect the overall form and characteristics of the bananas. Throughout the experiment‚ it was found that “Group 2 – Impact of Air Exposure‚” lasted longer than any other group. Following
