Separation Lab Purpose: 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 combined. All of these techniques involve changes in the physical state of a chemical compound rather than chemical changes. Sea sand‚ table salt‚ and two other unknown substances will be separated using the separation techniques in order to demonstrate

Abstract: Experiment 55 consists of devising a separation and purification scheme for a three component mixture. The overall objective is to isolate in pure form two of the three compounds. This was done using extraction‚ solubility‚ crystallization and vacuum filtration. The experiment was carried out two times‚ both of which were successful. Background Information: This experiment combined all the knowledge of the previous labs performed throughout the semester. An unknown mixture containing

PREPARATION OF ASPIRIN AND DETERMINATION OF THE MELTING POINT Ferrer‚ Lara Melissa V. Faculty of Engineering University of Santo Tomas Manila‚ Philippines ABSTRACT This experiment involved three steps: synthesis of aspirin‚ isolation and purification‚ and the estimation of purity of the final product. The synthesis involved the reaction of salicylic acid and acetic anhydride in the presence of a catalyst‚ phosphoric acid‚ H3PO4. When the aspirin was prepared‚ it was isolated and filtered. The percentage

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

materials we use today are actually mixtures of pure substances. The separation of these materials into their pure substances can be quite challenging. When we are discussing separations of a mixture that contains pure substances‚ it all depends on whether you can separate the substances by physical means. That means‚ utilizing each substances physical properties such as boiling point‚ melting point‚ and magnetism. Separation of a Mixture of Solids Lab Report Assistant
