Analysis of a Copper Sulfate Sample Essay

The purpose of this experiment is to find the empirical formula of a hydrous slovenly person sulfate specimen and the amount of water in the sample. This whole process will be determined in deuce-ace different experiments. ProcedureExperiment 1 per centum of water in sample.The percentage of water in hydrous hog sulfate was determined. undress, alter and weight the crucible past add sample of hydrous copper sulfate and reweigh crucible. light up the sample until it becomes white, which indicates that the water was removed. Let the crucible cool, then reweigh. Repeat until there is a constant temperature.Experiment 2 Percentage of copper in water in sample.Next the percentage of copper in the hydrous copper sulfate needs to be determined. Clean the glassware then get four 50 mL Erlenmeyer flasks with 25 mL of the stock solution and aqueous solvent. Prepare all the unfathomed sample solutions for determining Beers Law Graph. Turn on tintometer at 100% T then calibrate. Get the data and read it if it is reform.Experiment 3 Percentage of sulfate in sample.Weight come in the sample and dissolve it. Heat it and then slowly add the set up agent. Heat it for ab off 30 minutes while assembling the filtering device. Heat the aluminum pan with the filter, cool and then weigh it. Filter out barium sulfate solution, dry out filter and weight the sample and filter. Heat and weigh repeating until it is constant.Discussion and Errors The main error that occurred was that my attendant and I entered the wrong numbers in the Concentration section resulting in incorrect data. We put the incorrect concentration levels and we had no time to correct it. Everything in the calculation of the empirical formula came out precise though, with such(prenominal) little error. My highest error percent was Water with 1.5% which could have just been that I didnt burn it enough.
