    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 product obtained by distillation‚ is termed

    Chromatography is a process used to separate mixtures. The word chromatography is derived from the Greek words ‘khroma’ and ‘graphein’ meaning ‘color’ and ‘to write’ or to represent. Although there are a couple different types of chromatography‚ in each case a substance is placed onto or into a medium and a solvent is passed through the test substance. In chromatography science‚ the solvent is called the mobile phase or the carrier fluid and the medium is called the stationary phase. There are four

    SUMMARY The aim is to observe distillation process of ethanol-water solution and to measure the alcohol content after process in this experiment. 500 ml of solution with an alcohol content of 32% (v/v) is used for this experiment. Temperature values are recorded for every 10 ml alcohol obtained in the flask. The process is repeated in our experiment and for the first process‚ the data collection process continues until the distillate reaches to 200 ml. The concentration of alcohol is measured for

    Paper Chromatography Chromatography comes from the Greek word khromatos (color) and graphein (to write); i.e. paper chromatography is literally color writing on paper. This method tests the purity of compounds and identifies substances. This analytical process‚ despite having been replaced by the success of thin layer chromatography‚ still stands as a valuable teaching tool‚ and is nevertheless very common. This method is very useful because not only is it a relatively quick process‚ but also

    We reached our goals through our experimentation. We tested the solubility of each of the starting and ending materials in water‚ HCl‚ NaOH‚ toluene‚ and acetone. We discovered that the starting materials would only dissolve in toluene. To make the soap‚ we obtained about 10 mL of vegetable oil and 10 g of lard and we placed them both in separate 250 mL beakers. While we were stirring the compounds‚ we also added 15 mL of 6 M NaOH drop by drop and 1 mL of glycerol. We then heated our solutions

    Title: Distillation of an Ethanol Using Fractional Distillation Lab Report Abstract: This experiment aimed to separate the components of a mixture using Fractional Distillation. A volume of 28.0mL of a mixture including ethanol was heated until the temperature reached 78.0 C. Approximately 1.0mL of distillate was collected between 78.0 – 84.0 C. Percent composition by weight of the 1.0mL sample was determined to be 95% ethanol. By careful and accurate techniques‚ a high percent composition

    Abstract In this experiment paper chromatography was used in order to identify two unknown amino acids using eight known amino ones. The two unknown ones were identified by comparing the distance they travelled up the chromatography paper and their Rf values to the corresponding values of the other eight known amino acids. The unknown amino acids identified were Glycine and Methionine. Introduction Proteins in cells are important in many ways. There are different types of proteins such as
