2013 Lab report Isolating the Components of a Three Component Mixture The purpose of this experiment was to separate the component of three mixtures sand‚ sodium chloride and calcium carbonate then calculate the percentage by mass of each component recovered from the mixture. The other purpose of this experiment was to show us the students the concepts associated with physical and chemical properties of substances. Me and my lab partner‚ obtained a mixture of a un known proportion from the

09/18/2012 09/19/2012 Title: Separation of Mixtures and Solids Purpose: The purpose of this experiment was to practice the process of separating mixtures of different solids. Procedure: This experiment consisted of different processes to separate a mixture of solids into the four individual solids: sand‚ benzoic acid‚ iron fillings‚ and sodium chloride. To remove the iron fillings from the mixture I used a magnet and scanned it across the entire mixture and the magnet forced picked up

Quantitative Separation of a Mixture Lab Pre-Lab Questions: 1. Define the following: Physical Change Heterogeneous Mixture Sublimation Filtrate Residue 2. List two physical separation methods. 3. List the formula for determining percent composition by mass. Objectives: 1. to separate a three component mixture and 2. determine the percent composition by mass of each component in the mixture. Materials: Ammonium chloride (NH4Cl)‚ Sodium chloride (NaCl also known as

3Quantitative Separation of Mixtures This experiment performs the quantitative separation of thecomponents of a mixture. A mixture is the mixing of two or more substancestogether. The proportions of the components in the mixture can be varied.And the resulting mixture can be either homogeneous or heterogeneous‚depending on the properties of components such as solubility.In this experiment‚ you are going to separate a water-solublecomponent from water-insoluble components. The heterogeneous

calculations. Analysis/ Critical Thinking Questions: Compare your data for the pure substances with the data for each of the two solid mixtures. Which of the pure substances shows behavior that is similar to what you saw with the the two-solid mixtures (Mixture 1 and Mixture 2)? If you cannot positively identify your mixture‚ discuss the possibilities for the mixture. The starch and mixture 2 are both similar because they both did not penetrate when the vinegar was added; when the water was added the laid on

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

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

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 and

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.

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
