Experiment Separation of Organic Compounds by Acid-Base Extraction Techniques 5 A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction techniques to separate a mixture of an organic acid‚ a base‚ and a neutral compound. Organic acids and bases can be separated from each other and from neutral compounds

Separation of a Mixture: Unknown # 12-Green Chemistry 221 with Professor Thomas Quale May 2012 Formal Lab Report Abstract An unknown sample‚ # 12-Green‚ was separated into its individual variable components‚ iron‚ ammonium chloride‚ silicon dioxide‚ and sodium chloride. The techniques used to separate the components of unknown # 12-Green‚ magnetism‚ sublimation‚ extraction‚ and filtration‚ were chosen based on the unique properties of each component. Using these separation techniques‚ each substance

Purpose: In this lab‚ a mixture of naphthalene (C10H8)‚ common table salt (NaCl)‚ and sea sand (SiO2) will be separated using the separation techniques in order to demonstrate the properties of mixtures and their ability to be separated by physical means. INTRODUCTION: This lab was based on the separation of the components of a mixture. A mixture can be defined as a physical combination of two or more pure substances. Separation techniques are used to separate components that are not chemically

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

Separation of Iron‚ Salt and Sand Separating a mixture is an example of a physical change. There are several ways to separate a mixture. The use of one’s hands in pulling the parts of a mixture apart is one example. Filtration is another way to separate mixtures. Filtration is the separation of a heterogeneous (not alike‚ different) mixtures‚ by adding a solvent and passing the resulting mixture through a fine mesh or filter. Evaporation of a homogeneous (alike‚ same) mixture will reveal

Types of Mixtures Lab Purpose • To classify types of mixtures • To determine the polarity of substances Background Information: Polarity In the middle of the night of March 24‚ 1989‚ the giant oil tanker Exxon Valdez veered out of the shipping lanes in Alaska’s Prince William Sound and struck a reef. The side of the tanker was ripped open‚ and 11 million gallons of crude oil flowed out into Alaska’s clear blue waters. Because petroleum oil is insoluble (does not dissolve) in water and less

Mixture separation Lab I am one of the chemists assigned to design a cost effective procedure for handling the CARBOSE separation and recovery and hazardous waste disposal. The difficulties were trying to figure out is how we can effectively separate Carbose‚ sand‚ and naphthalene? The hypothesis we chose to solve this problem was if we put the mixture into water‚ alcohol‚ and mineral spirts‚ then in each solution one or more substance will not dissolve‚ will be visible‚ and also able to separate

Abstract: This lab experiment was conduct and taught based upon the primary instruction and introduction to mixtures. With this lab I was able to determine and execute the proper separation of a mixture of solids through various means‚ such as evaporation and filtration. Using these techniques presented the separation of different ingredients from a mixture was conducted based upon the usage of individual physical properties of each substance presented in the mixture. . Observations: Throughout

Craig Delancy Separation of a Mixture Containing Calcium Carbonate and Naphthalene Objective: Finding a method to successfully separate a mixture of calcium carbonate and naphthalene. Properties to be considered: Calcium Carbonate Naphthalene Solubility in water slightly insoluble Solubility in ethanol insoluble partially Melting point 825 degrees C 80.2 degrees C Boiling point decomposes 218 degrees C Procedure: Subliming the mixture seemed to be the most

Purpose: The purpose of this separations lab was to see what the most efficient way is to separate a dry mixture using all kinds of materials. The mixture was of salt‚ sand‚ iron filings‚ and bird seed. Results: The results of mass recovered were very different from what the actual mass was. The iron filings were about the same besides recovering 0.1 extra gram. For the bird seed‚ there was 0.7 grams more collected from the original mass that is 2.0 grams. The sand had 2.5 grams recovered‚ where
