Iron & Coppersulfate

Introduction Making observations are very important in chemistry. It should be done carefully and precisely to ensure no mistakes. This experiment was all in all approximately observing. In this experiment, a set of chemics were used to set up an experiment. The experiment was observed for three days. The chemicals used were copper sulphate ( blue(a) crystals), sodium chloride (salt), and exhort.Copper convert is a chemical compound which is produced commercially by reacting various copper (II) compounds with sulfuric acid 1. It generally appears as a bright blue or green crystal 1. Its chemical approach pattern is CuSo4. Iron is silver-white magnetic metallic and readily rusts in moist fashion 3. Its chemical formula is Fe. The chemical reaction was demonstrated by the press reacting to the copper sulfate. Copper Sulfate Crystals 4 Materials & MethodsMaterials 2 minute circles of gain vigor paper, 1 iron narrow, 5 grams of copper (II) sulfate, 10 grams of sodium chloride (salt), and 1 small piece of plastic wrap Method Briefly, 5 grams of copper (II) sulfate was pose in a analyse tube. Filter paper was placed on top of that, 10 grams of salt were then added, and then to a greater extent filter paper was added. An iron nail was placed faced carry out on top of that last filter paper and then the demonstrate tube was filled with enough water to cover up the nail. Last, the test tube was observed for the next three days.Results Time Observation day 0 * The tip of the nail had turned pinkish-red * The bottom of the tube, which was clear and blue from the copper sulfate was now bright green Day 1 * The entire nail was now pinkish-red * Some copper had shed mop up of the nail and was resting on top of the salt * The water turned white-livered * The tube is now dark-almost black green at the bottom * in that respect was less copper sulfate Day 2 * The entire nail was pink * The water was still yellow * A lot of copper has shed from the nail *The co pper sulfate has dissolved (it is only about 1 gram left) The above can be summarized by this chemical reaction Fe(s) + CuSo4(aq) Cu(s) + FeSo4(aq) iron copper (II) copper iron (II) sulfate sulfate Discussion The purpose of this experiment was to show how iron reacts to copper sulfate. It seems ilk iron got jealous of copper sulfates chemistry so iron stole sulfate from copper. Thats how iron sulfate came to be and that is also why copper is now alone. The purpose of the salt was to dim the reaction down.The purpose of the water was to dissolve the copper sulfate. The purpose of the filter papers were to separate the chemicals. The evidence of the change that was observed was that there was no more copper sulfate but there was now iron sulfate.
