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

Recrystallization of Benzoic Acid Objective To purify benzoic acid by recrystallization and gain experience with a basic organic laboratory techniques. Background Products of chemical reactions are often contaminated with impurities. One method for purifying chemicals‚ recrystallization‚ takes advantage of the differences in the solubilities of the desired products and the impurities and the tendency for the slow formation of crystals to exclude impurities from the crystalline solid.

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.

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

NANCY MARASHI. | Background: During this experiment students will take a mixture and separate it into its’ pure substances. A mixture is a combination of two or more substance. These substances cannot be combined chemically but more physically. The pure substances are substances that cannot be separated any more by physical means. The students

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

Experiment 1: Purification of Benzoic Acid by Recrystallization III. Introduction Purification - physical separation of impurities and by-products from an impure sample pure substance. *Distillation- for liquid compounds‚ *Recrystallization- solid compounds Recrystallization - precipitation of a solid cpd. from a saturated solution in the form of crystals through cooling or evaporation -7 steps: 1) selecting the appropriate solvent 2) dissolving the solute 3) decolorizing the

Experiment 1 Separation of Mixtures Summary of Principles: Most of the materials we encounter in everyday life are not pure substances. Many materials such as sand are formed from physical combination of various substances‚ and are called mixtures. Mixtures can be classified into homogeneous and heterogeneous. The purpose of this lab is to learn how to separate individual components from a mixture through decantation‚ filtration‚ distillation‚ and crystallization. Pre-Lab Questions: Attached
