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

Making homemade liquid soap is not as challenging as you may think. With just a few ingredients and a little bit of time‚ you can make your own liquid soap right in the comfort of your home. If you are looking to save some money‚ or just want a fun project to do at home‚ you can create a homemade product that works just as well as commercial-grade soaps at a fraction of the cost. You will need to spend some money upfront‚ but you can make several batches of soap with the ingredients. Bar soap works

Who doesn’t love to read a good magazine? In Women’s Day there was an ad about Liquid Plumber‚ and good gracious there’s a sexy man on the cover. It quotes “Only have 10 minutes? I only need 7.” In the ad his name is Rusty‚ and he is well groomed. Rusty has a chiseled body his shirt tucked in; with just a little bit of chest hair sticking out. Those hip hugging blue jeans are a plus as well! His hair looks like it has been played with and he has a seductive smirk on his face. Most women would stop

The study of shelf life for liquid biofertilizer from vegetable waste showed that contrary to the traditional advice that liquid biofertilizers produced from fermentation by effective microorganisms‚ should be used within three months of production‚ the liquid biofertilizer produced from vegetable waste still contains high amount of viable microbial population after four months of storage with no significant effect of the presence or absence of light (Ngampimol and Kunathigan‚ 2008). The most common

Discuss some of the concerns and anxieties aroused by the emergence of ’mass culture’ There has always been a definitive struggle to define culture as it is so complex and means something different to each individual. Culture affects all of us in different ways resulting in multiple definitions of culture. Culture had previously been seen as a way of improvement and growth‚ helping us to understand our place in society and guiding us towards a better understanding of ourselves. Over the previous

Determining the Absorbance Maximum Wavelength and Molar Extinction Coefficient to Find the Molarity of the Unknown DCPIP Background Information: A spectrophotometer is an instrument used to help determine the absorption spectrum of chemicals. It does this by reading the absorbance of the chemical at different wavelengths. All chemicals absorb light in their own distinct way. This distinction helps to identify unknown chemicals. The absorption of light within a chemical is also very important because

The Separation of a Liquid Mixture by Simple Distillation Objective The purpose of doing this experiment is to separate two miscible liquids samples of cyclohexane and toluene using simple distillation. The objectives will be to record boiling range and volumes (mL) of distillates that are attained during the process of distillation. Background Distillation is a frequently used technique for separating mixtures based on differences in the boiling points of components in the mixture. The
