PRINCIPLES OF CHEMISTRY LAB I Experiment 2 Separation Of Mixtures INTRODUCTION A mixture can simply be defined as a substance that is made up or consists of two or more elements and/or compounds that are physically combined but that have not reacted chemically to form new substances. A mixture may be a solid‚ liquid‚ gas‚ or some combination of those states. Mixtures can be found almost every wher in our everyday lifes and some common examples are * sand and water * salt and water

February‚ 9 2011 Lab report on separation of mixtures Purpose- The purpose of this lab is to separate or isolate the desired product from large amounts of solvent and by-products. It is also followed by a purification step that removes trace amounts of other substances from the final product. One of the experimental techniques that we used in the lab to separate or purify mixture is fractional crystallization. In the experiment we used fractional crystallization to resolve a mixture of salicylic acid

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

Gorman and Tyler Kui) Lab #1: Separation of a Mixture Mr. Mejia 10/3/14 Separation of a Mixture Lab Report Abstract The purpose of the experiment was to separate an initial heterogeneous mixture composed of 5.00 grams of salt‚ 2.00 grams of sand‚ 50.0 mL of water‚ 15.00 grams of pebbles‚ and 1.00 gram of iron filings‚ and leave as much salt as possible remaining. Using separation techniques including magnetizing‚ evaporation‚ filtration‚ etc. the heterogeneous mixture was thoroughly separated

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

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

DISTILLATION- SEPARATION OF A MIXTURE Ronald Ogbu‚ Alex 27th Aug. 2013 Purpose: To separate mixture of acetone and toluene using simple‚ packed and unpacked distillation columns. Results and Discussion: There were three distillation setups: simple‚ unpacked and pack fractional. All three procedures had different distillation apparatus but the unknown mixture was the same for all. The unknown liquid in a 50 ml round bottom flask was heated in a heating mantle such that a

Separation Techniques If one component of the mixture has magnetic properties‚ you can use a magnet to separate the mixture. Cobalt‚ iron and nickel all have magnetic properties. Note that not all metals are magnetic and magnetism is not a method to separate metals from non-metals. Gold‚ silver and mercury are examples of non-metal substances. Magnetism is however a way to separate magnetic substances from non-magnetic substances is. Magnetism as a separation method is done by taking any magnetic

Separation of the Components of a Mixture Purpose: To become familiar with the methods of separating substances from one another using decantation‚ extraction‚ and sublimation techniques. Apparatis and Chemicals: balance‚ Bunsen burner‚ rubber hose‚ tongs‚ 2 evaporating dishes‚ 2 watch glasses‚ 100-mL graduated cylinder‚ clay triangles‚ 2 ring stands‚ 2 iron rings‚ 2 glass stirring rods‚ unknown mixture of NaCl‚ NH4Cl‚ SiO2. Discussion: Mixtures are composed of two or more substances

Separation of Mixtures Mixtures exist in many forms in the world‚ and if it were not for methods of separation‚ many of these substances would be meaningless to us. Separating mixtures is extremely important to human lives; for example‚ many people filter water so that it is safe for drinking. Mixtures contain two or more substances that are not in a fixed ratio‚ and while some mixtures‚ such as concrete‚ are useful‚ others including salt water‚ are not as useful to us. Filtration‚ distillation
