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

Purpose and Audience: 1. I think this is aimed at a general audience because it covers many different jobs and different examples. 2. In a hierarchy every employee tends to rise to his level of incompetence. Late in the story. I think they did this to lay the groundwork and to make you come to his way of thinking before he pitched it. 3. I think they are pretty serious overall‚ and they are there to instruct and entertain. Style and Structure: 1. So you get where they are coming from

Title: Spectrophotometric analysis of a two-component mixture Aim: i. To prepare working standards of dichromate and permanganate ii. To measure the absorbance of the prepared working standards of dichromate and permanganate using a spectrophototometer iii. To determine the concentrations of permanganate in a mixture of unknown. Abstract: Working standards of dichromate and permanganate were prepared and absorbance for each found. This was done in order to plot

Exp. 2 Separation of Three Compounds by Extraction Introduction: The purpose of this experiment is do demonstrate the proper procedures of extraction and to develop a practical understanding of this method. In this experiment‚ extraction is used to separate a known acid‚ base‚ and neural compound from each other. The first two compounds undergo proton transfer reactions in the presence of acids or bases. Acids RCOOH‚ like benzoic acid‚ was deprotonated to form RCOO-. Bases RNH2‚ like ethyl 4-aminobenzoate

Experiment 1: Simple and Fractional Distillation of a Binary Mixture Introduction: In this experiment the aim is to separate two chemicals from a stock mixture (azeotrope) using two different distillation processes. In both methods (simple and fractional) the liquids reach a boiling point‚ the molecules then vaporize‚ separate from the stock mixture and then condense back into liquid form down the to the receiver. Simple distillation works well when the two components boiling points have a large

Analysis of Soda Ash and Carbonate-Bicarbonate Mixture Submitted: February 27‚ 2013 Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas España‚ Manila Abstract A standard acid solution like HCl can be used as titrant for the analysis of both soda ash and a carbonate-bicarbonate mixture. In the analysis of soda ash‚ the volume needed to neutralize the soda ash is used to compute for its alkalinity‚ in this experiment we obtained a 17.6 % alkalinity with an error
