Separation of a Mixture of Solids My Flow Chart First remove iron filings with magnet since this is the only substance in the mixture that it is magnetic and will be attracted to a magnet. Second remove the sand by adding the mixture to hot water‚ which the other two substances are soluble. Third remove the benzoic acid since this is less soluble in cold than salt by cooling the mixture in the heated water. This will then leave the table salt behind in the water as the last substance.

Abstract By separating chemicals out of a mixture and purifying them through sublimation and recrystiliation‚ changes in the substances physical properties can be shown. A salicylic acid-naphthalene mixture was mixed together with diethyl ether and saturated sodium bicarbonate. Two layers separated and were extracted after acidifying with HCl. This precipitated the crude salicylic acid. The left over mixture was combined with water and the two layers separated where crude naphthalene was recovered

– Separation of a Mixture of Solids Cathy Lab Partners: Chelsea Brooke Sept 4‚ 2012 Chemistry 131A Dr. Vicki H Audia Pelab Questions: Proposed procedure for separation of a mixture: Use physical properties of the 4 substances to separate. 1. Remove iron with magnet 2. Add water to the mixture to melt the benzoic acid and NaCl then filter out sand. 3. Chill the solution and scoop the acid out leaving a salt solution. 4. Boil water away leaving salt. Purpose: The purpose

Title: Separating the components of “Panacetin” Name: Ip‚ Wing Chung (Vincent) Lab Partner: Ma‚ Siyin Date: 2/3/2013 Introduction: The purpose of this experiment is to investigate the composition of compounds in Panacetin. Generally‚ it is made up of sucrose‚ aspirin and an unknown component‚ either acetanilide or phenacetin. SinceBy using different techniques‚ such as filtration‚ extraction‚ and evaporation‚ those three components have been isolated out‚ which is based on varies solubility

INTRODUCTION 1.1 General Foundry sand is high quality silica sand with uniform physical characteristics. It is a byproduct of ferrous and nonferrous metal casting industries‚ where sand has been used for centuries as a molding material because of its thermal conductivity. It is a byproduct from the production of both ferrous and nonferrous metal castings. The physical and chemical characteristics of foundry sand will depend in great part on the type of casting process

Samantha Smith Organic Chem 255 Lab M/W 12:30-4:30 Hyejin Cho 12 June 2013 Separation of a Mixture Abstract: In this experiment‚ the three processes of extraction‚ sublimation and recrystallization will be used to separate a mixture of salicylic acid and naphthalene. The first part of extraction will be to separate the salicylic acid from the naphthalene using diethyl ether and aqueous sodium bicarbonate. The naphthalene will reside in the ether and be the top layer‚ while the

Genevieve Sierra Chemistry seg. 2 June 15‚ 2014 05.05 mixtures and solutions: Lab report: outline Ink chromatography Chromatography is the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates. It is used to separate substances. Examples of chromatography are finger-printing‚ medicines‚ and separating/ testing histamines. http://www.biotecharticles.com/Agriculture-Article/Applications-of-Chromatography-1299

The Separation of Mixtures This lab demonstrates the difficult task of separating mixtures using different types of methods. This study is performed because it helps you understand the concept of separation and certain characteristics of elements. Previous knowledge in which already exists in this lab would be the process of filtration‚ distillation‚ magnetism‚ and evaporation. The specific hypotheses of this experiment was that the iron would separate through magnetism‚ the salt would separate
