Analysis of a Copper Sulfate Sample Essay

The intention of this experiment is to find the empirical conventionality of a hydrous crap convert ensample and the amount of body of urine in the sample. This whole process will be determined in three opposite experiments. Procedure try come forth 1 parcel of water in sample.The pct of water in hydrous sloven convert was determined. lite, dry and weight the crucible wherefore add sample of hydrous copper sulfate and reweigh crucible. love the sample until it becomes white, which indicates that the water was removed. Let the crucible assuredness, then reweigh. recall 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 quadruplet 50 mL Erlenmeyer flasks with 25 mL of the stock solution and aqueous solvent. jell all the unknown sample solutions for ascertain Beers Law Graph. Turn on colorimeter at 100% T then calibr ate. Get the data and take apart it if it is class.Experiment 3 Percentage of sulfate in sample.Weight aside the sample and dissolve it. Heat it and then easily add the precipitating agent. Heat it for active 30 minutes while set up 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(prenominal) error that occurred was that my partner and I entered the treat numbers in the Concentration piece resulting in inaccurate data. We put the incorrect concentration levels and we had no time to correct it. Everything in the calculation of the empirical face came out precise though, with such diminished error. My highest error percent was Water with 1.5% which could check just been that I didnt give the axe it enough.
