Copper/Iron Stoichiometry Drew Bloomquist BB7 September 17, 2012 Abstract: In this lab, students descend a hold reagent though experimental modus operandi development quantitative transfer and vacuum filtration. Iron toilette rule more(prenominal) than one ion which means it can form more than one compound with sulfate. The limiting reagent depart be contrastive depending on which compound squeeze forms. Vacuum filtration uses ii flasks, hose, a glass crucible and vacuum in fix up to separate the boil down formed in the answer from the solution. weigh by difference uses a pan balance, analytical balance, beakers and advisement bottles to precisely measure the plenitude of smoothing compress and bull (II) sulfate. The mass of copper (II) sulfate was 6.9884 g and the mass of iron was 1.9970 g which yielded 2.7383 g of copper. The blue color of the solution subsequently the precipitate response verified that the reaction formed iron (II) sulfate. CuSO4 (aq) + Fe(S) Cu(s) + FeSO4(aq) cosmos: In this experiment, stoichiometric ratios are employ to bound the limiting reagent of the reaction. Stoichiometric ratios are ratios that are determined by the coefficient of reagents in chemical equations. These ratios can be used to determine the phone number of moles and mass of the products. Limiting reagents are reagents that will be used up first in the reaction and will pee the reaction to stop. The limiting reagent will be determined done experimental procedure. Iron can take two compounds with sulfate.
