Reaction of Iron Filings with an Aqueous Solution of Copper (II) Sulfate Purpose: There were many reasons that we conducted this reaction as a lab. The main objective of the lab was to observe a reaction of Iron and Copper (II) Sulfate. This lab presented a good opportunity to work with numbers using moles and Stoichiometry. This lab was also good for practice using Bunsen burners, glass, and handling hot objects. Lastly, we got to witness and test the Law of Conservation of Mass through the reaction in this experiment. The list goes on, but these are just a few objectives from the recently conducted lab experiment. Background: Before this experiment we had knowledge on the safety of most of the materials we worked with. Copper (II) Sulfate is harmful by inhalation or ingestion. Iron (II) Sulfate is also harmful if ingested, and could cause death. It can be used as a nutrient and agriculturally. Copper (II) Sulfate Pentahydrate is used in agriculture as a pesticide, germicide, feed additive and soil additive. (http://chemicals.etacude.com/c/copper_sulfate2.php) Mole- a chemical mass unit, defined to be 6.022 x 1023 molecules, atoms, or some other unit Molar Mass- the mass of one mole of a substance Balanced Equation- an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products Oxidation Reduction Reaction- a half-reaction in which a chemical species decreases its oxidation number, usually by gaining electrons. Single Replacement Reaction- a reaction is characterized by one element being replaced from a compound by another element. Mole Ratio- the ratio of the moles of one reactant or product to the moles of another reactant of product in the balanced equation for a chemical reaction Stoichiometry- the process of using chemical equations to
