Lab #2 – Separation of a Mixture of Solids Abstract The mixed solution contained benzoic acid‚ iron‚ table salt‚ and sand. When separated using water‚ fuel‚ or a magnet‚ their characteristics and properties changed. The mass of the entire mixed solids was 6.6 grams. When the magnet was used‚ the iron was immediately picked up. The mass for that was 1.7 grams. The table salt was 1.2 grams. Benzoic acid mass was 0.8 grams and the sand was 1.4 grams after being separated. Introduction The objective

Separation of Mixtures and Solids Purpose: To become familiar with the separation of mixtures of solids Hypothesis: I will be able to separate the materials using a variety of different methods. First‚ separate the iron fillings using a magnet. Second‚ I will put the rest of the solution into water and separate the insoluble sand from the soluble salt and benzoic acid. Third‚ I will filter out the benzoic acid when crystalized. Lastly‚ I will evaporate the water away leaving crystallized salt. Procedure:

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

(example: hydrogen) or a gas (example: Hydrogen). Matter can be classified as either a mixture or a pure substance or a mixture. There are two types of mixtures a homogenous mixture and a heterogenous mixture. A homogenous mixture is a mixture that has been thoroughly combined and has been turned into a solution. A heterogenous is a mixture in which the particles has not been thoroughly combined. All mixtures can be separated to get the back to its original form - a pure substance. A pure

Chemistry assignment: The mixture selected in this assignment is seawater obtained from the hydrosphere. The seawater can be separated through out several processes‚ both chemically and physically. The separation process is known as desalination. This name is getting more common everyday‚ as the Australian water demand grows with population we can no longer ignore the salinity problem. Desalination process could take use of the salt concentrated water‚ turning them into fresh water. Industrial

CHM 266 Section 4 Experiment#: PROP0375 Separating the Components of a Ternary Mixture Hassan Alhammad 2554122 T.A Katherine Turner 9/11/2014 Introduction The purpose of the experiment is to separate components of mixture of sand (SiO2)‚ salt (NaCl)‚ and chalk (CaCO3). 1. CaCO3+2HCl-----CaCl2+CO2+H2O 2. CaCl2+K2CO3====CaCO3+2KCl The first reaction shows the separation of calcium carbonate from the mixture. In the second reaction we use the product of the first reaction (CaCl2)

Separation of a Mixture of Solids I really enjoyed this lab. After reading the introduction I started by making my own flow sheet of how I thought this lab would work. I was reminded about solubility which is defined as the amount of the solute that will dissolve in a given amount of solvent and that the extent to which a substance dissolves depends mainly upon the physical properties of the solvent and of the solute and to some extent upon the solvent’s temperature. With that being said I came

Separating The argument of the confusion of the family brought up by John Updike in his essay‚ “Separating”‚ has many strengths seen through the characters themselves and their actions. Updike displays the family of confusion through the use of pathos seen through the characters‚ disconnection of the family members‚ and a crumbling down relationship between Richard and Joan. Updike uses pathos to describe the family as confused and lost to ultimately bring together an understanding of the separation
