Experiment 2: Copper/Iron Stoichiometry
Abstract:
The purpose of the Copper/Iron Stoichiometry lab was to determine which of the two possible iron sulfate compounds formed when reacting aqueous copper(II)sulfate with solid iron metal. The techniques used in this lab were weighing by difference, quantitative transfer, and vacuum filtration. At the end of the experiment it was found that iron was the limiting reactant and iron(II)sulfate was a product of the reaction between 7.0002g of copper(II)sulfate and 2.0101g iron metal which produced 2.3037g of copper product with a percent yield of 100.72%.

Much research has gone into studying how to best utilize the degradation abilities of various bacteria and fungi. …show more content…
The limiting reagent is determined by first using the “weighing by difference” method, which is when one measures a substance by comparing the difference in its mass before and after transferring it to another container. To later collect the copper product produced in the reaction, quantitative transfer was employed to completely remove the copper product from the beaker and into the vacuum filtration apparatus, a technique used to separate different substances through the use of a filter and vacuum. After having performed the vacuum filtration, the percent yield of the reaction could be measured and consequentially the limiting reactant of the reaction between CuSO4 and Fe could be …show more content…
In relation to the lab, a weigh boat was placed on the analytic balance and a little over 7g of CuSO4 was added, the balance was then tarred and CuSO4 was removed from the weigh boat and into a 150ml beaker until the scale read as close to -7.0000g as possible, for this experiment 7.0002g of CuSO4 was used. The same procedure was used to measure 2.0000g Fe and 2.0101g was obtained. Once the CuSO4 and Fe were mixed, the solid product was collected using a vacuum filtration apparatus because it is the most effective method of separating a solid from a solvent. Quantitative transfer was implemented to insure that all the Cu was moved from the beaker to the crucible by rinsing the beaker several times with DI water then running the rinse through the vacuum filtration apparatus to collect any leftover
