Filtration – This is an experiment in which inorganic and displacement chemical reactions take place to collect a salt and produce water through the process of filtration. The chemicals used were a metal oxide, in this case copper. oxide and a dilute acid, sulfuric acid, aimed at separating copper and oxygen to collect pure copper (II) ions, which is a soluble salt. The color should be a very characteristic blue. Sulfuric acid is added to a beaker. A tripod and Bunsen burner are set up and the beaker is heated with the blue flame of the Bunsen burner until it boils. Then a spatula is needed to add portions of the copper(ii) into the beaker, stirring continuously for about thirty seconds and adding the next portion, and stirring and so on until all the copper oxide copper has been added. The beaker is then heated for a few more minutes, to ensure that the copper oxide has completely reacted with the sulfuric acid. The next step of the experiment requires placing a filter funnel into the neck of the conical flask. The filter paper should be folded into the funnel. The contents of the bowl should still be warm. This is stirred and slowly filtered into the funnel. A light blue solution should end up in the funnel. If black powder is found in the solution, filtration should be repeated. The clear solution is poured into a beaker and left in a warm place for about a week to allow the water to evaporate. The crystals will begin to form as they dry, so they should be filtered and the crystals should be collected on a paper towel to absorb any excess water. (Nuffield Foundation, 2011)(Nuffield Foundation, 2011)ChromatographyThis is a technique which is used when separating mixtures. A substance is placed in a paper medium with ice water. The vacuum cleaner stays on to dry the aspirin. For it to be completely dry, you may need to let it sit for a whole day. Distillation The purpose of distillation is to separate mixtures and purify liquids. A distillation experiment was done in class to extract limonene from orange peel. (Zamcopter, 2014) The distillation process begins by putting the orange in a blender. The bracket and clamp are attached to the round bottom flash and the distribution tube. The orange zest is now put at the bottom of the flask with boiling water. This must be brought to reflux for thirty minutes, which cools and captures the vapors formed. The equipment is rearranged according to the picture below and the collected substance, limonene/water distillate, is collected in the boiling tube. (Expats, 2014) Bromine water is added drop by drop to the distillate..
