Chem 1211L Mrs. Amy Cook 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

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

SEPARATION OF MIXTURE OBJECTIVE: To separate the components of a mixture based upon physical characteristics of each component within the mixture. Secondly‚ to determine the mass of each component by using the knowledge of separation techniques. SAFETY REQUIREMENTS: Do Not Pipette By Mouth Read the Chemical Safety Information Dress Appropriately Identify the Safety Equipment Don’t Taste or Sniff Chemicals Don’t Casually Dispose of Chemicals Down the Drain MATERIALS:

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

include solubility‚ boiling point‚ melting point etc. By taking advantage of the unique physical properties of individual components within a mixture‚ it should be possible to separate a mixture into its components and they can be used by different separation methods - one example is a strainer. Physical changes that can be used to separate the components of a mixture including filtration‚ evaporation‚ crystallization‚ and distillation. Mass percent composition is a convenient way to express that actual

Experiment 3: Separation of the Components of a Mixture General Chemistry 101 (CHEM 101)‚ ISP SCUHS Report 2 September 15‚ 2013 Abstract Mixtures are made up of substances or components. If the mixture is fairly uniform in composition‚ properties‚ and its overall appearance‚ it is homogenous. If the component parts are clearly separated‚ it is heterogeneous. In order to identify the components in a mixture‚ methods must be used to sort out the components. However‚ the same methods will not

Title: Lab #3 Separation of a Mixture of Solids Purpose: To understand the different separation methods and techniques that depend on the chemical properties of a specific substance. Also to become more comfortable with performing those actions of separation so I have them in the future. For this experiment‚ I will separate a mixture of four distinct substances: sodium chloride‚ benzoic acid‚ silicon dioxide‚ and iron fillings into pure beings. Procedure: Materials: distilled water coffee

Industrial Separation Research a) Identify a mixture that is separated industrially: Olive oil b) Identify which ‘sphere’ it is obtained from: Biosphere c) Identify the industrial separation processes used on this mixture: Crushing/grinding: The olive fruit is crushed and ground by a metal hammer in a mill to make a paste. Beating: The olive fruit paste is added to water is additionally beaten to extract more oil from the olive cells. Salt can be used to assist osmotic breakdown [of the cells]
