Lab 3 – Separation of a Mixture of Solids Cathy Lab Partners: Chelsea Brooke Sept 4‚ 2012 Chemistry 131A Dr. Vicki H Audia Pelab Questions: Proposed procedure for separation of a mixture: Use physical properties of the 4 substances to separate. 1. Remove iron with magnet 2. Add water to the mixture to melt the benzoic acid and NaCl then filter out sand. 3. Chill the solution and scoop the acid out leaving a salt solution. 4. Boil water away leaving salt. Purpose: The

Experiment 2: Separation of a Mixture of Solids Purpose: This experiment allowed me to learn different separation techniques for various substances based on their specific chemical properties. Procedure: I began this experiment by using a magnet to pick up and collect the iron filings out of the mixture. Then the sand was separated by placing the mixture into a beaker and boiling it in distilled water in order to dissolve the salt and benzoic acid‚ once boiling the liquid was poured out leaving

Separation of a Mixture: Unknown # 12-Green Chemistry 221 with Professor Thomas Quale May 2012 Formal Lab Report Abstract An unknown sample‚ # 12-Green‚ was separated into its individual variable components‚ iron‚ ammonium chloride‚ silicon dioxide‚ and sodium chloride. The techniques used to separate the components of unknown # 12-Green‚ magnetism‚ sublimation‚ extraction‚ and filtration‚ were chosen based on the unique properties of each component. Using these separation techniques‚ each substance

Types of Mixtures Lab Purpose • To classify types of mixtures • To determine the polarity of substances Background Information: Polarity In the middle of the night of March 24‚ 1989‚ the giant oil tanker Exxon Valdez veered out of the shipping lanes in Alaska’s Prince William Sound and struck a reef. The side of the tanker was ripped open‚ and 11 million gallons of crude oil flowed out into Alaska’s clear blue waters. Because petroleum oil is insoluble (does not dissolve) in water and less

LS 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

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

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
