1 STOICHIOMETRY: The Reaction of Iron with Copper (II) Sulfate Introduction In this experiment we will use stoichiometric principles to deduce the appropriate equation for the reaction between metallic iron and a solution of copper (II) sulfate. This reaction produces metallic copper, which is seen precipitating as a finely divided red powder. This type of reaction, in which one metal "displaces" another from a solution of one of its salts, is known as a single substitution reaction. A metal capable of displacing another from a solution of one of its salts is said to be "more active" than the displaced metal. In this experiment, iron is more active than copper. Iron forms 2 types of ions, namely Fe +2 and Fe +3. We shall use stoichiometric principles to determine which of these ions is formed in the reaction between iron and copper (II) sulfate solution. If Fe +2 is formed, then equation (1) is correct, while equation (2) is correct if Fe +3 is formed. Your task is to find out which equation is consistent with the results of your experiment. (1) Fe (s) + CuSO 4 (aq)! FeSO 4 (aq) + Cu (s) Fe (s) + Cu +2 (aq)! Fe+2 (aq) + Cu (s) (2) 2Fe (s) + 3CuSO 4 (aq)! Fe 2 (SO 4 ) 3 (aq) + 3Cu (s) 2Fe (s) + 3Cu +2 (aq)! 2Fe+3 (aq) + 3Cu (s) An excess of copper (II) sulfate solution (to make sure that all the iron is reacted) will be added to a known amount of iron. The metallic copper produced will be weighed. These weighings will be used to calculate the moles of iron used and the moles of copper formed. If equation (1) is correct, the moles of copper should equal the moles of iron. If equation (2) is correct, we should obtain 1.5 moles of copper per mole of iron.

4 Results 1. From your data, which equation (1) or (2) gives the correct stoichiometry for this reaction? Explain your answer. 2. What evidence indicates that a chemical reaction has occurred? 3. State two reasons why you may not recover the theoretical amount of copper in this experiment.

5 Prestudy Name Section The Reaction of Iron with Copper (II) Sulfate Copper can form two possible cations, cuprous (Cu +1 ) and cupric (Cu +2 ). When solid copper is reacted with a silver nitrate solution, two reactions are possible, as shown in the following equations: a. AgNO 3 (aq) + Cu (s)! Ag (s) + CuNO 3 (aq) Ag +1 (aq) + Cu (s)! Ag (s) + Cu+1 (aq) b. 2AgNO 3 (aq) + Cu (s)! 2Ag (s) + Cu(NO 3 ) 2 (aq) 2Ag +1 (aq) + Cu (s)! 2Ag (s) + Cu+2 (aq) 1.(3 points) How many grams of metallic silver can form from g of copper metal according to equation (a)? 2.(3 points) How many grams of metallic silver can form from g of copper metal according to equation (b)? 3.(4 points) A student reacts grams of copper with a solution containing excess silver nitrate and recovers g of silver metal. Which reaction, (a) or (b), most likely occurred in his experiment? Explain your answer completely.
