INTRODUCTION Extraction is a method of seperation in which a solid or solution is contacted with a liquid solvent (the two being mutually insoluble) to transfer one or more components into to the solvent. There are two main types of extraction in chemistry‚ namely: Liquid-liquid extraction or solvent extraction‚ which is divided into two types. (simple and multiple) and solid-liquid extraction. The type of extraction that was used in this experiment was the solid-liquid extraction. To extract the caffeine

PR OCEDURE Before beginning‚ set up a data table similar to the Data Table: Experiment Results in the Lab Report Assistant section. This experiment will create a reaction of sodium carbonate and calcium chloride dihydrate to produce a precipitate of calcium carbonate. This formula is: Na2CO3(aq) + CaCl2. 2H2O(aq) à CaCO3(s) + 2NaCl(aq) + 2H2O 1. Put on your goggles. 2. Weigh out 1.0 g of CaCl2·2H2O and put it into the 100-mL beaker. Add 25 mL of distilled water and stir to form the calcium
