Experiment Separation of the Components of a mixture Initial Statement: In this experiment, a mixture of ammonium chloride, sodium chloride and silicon dioxide will be used in a quantitative analysis to determine the percentage of mass from each component. The ammonium chloride will be separated from the mixture through sublimation. The sand is separated from the salt using dissolution and filtration. In the final technique, elevated temperature is used to isolate the salt from the remaining water. Percent equation: % component = wt component in grams / wt sample in grams x 100 Special equipment: Bunsen burner, 150 mL beakers, and filter paper. Procedure: A 150 mL beaker will be weighed to the nearest 0.01gram. The beaker will be weighed again with the mixture to the nearest 0.01gram in order to determine the mass of the mixture. A ring stand, wire gauze and Bunsen burner will be set up in the fume hood for the purpose of drawing the fumes out of the room. The 150 mL beaker containing the mixture is placed on the ring stand. The Bunsen burner is hooked up to the methane outlet and then turned on by placing a lighted match near the top of the stack.
