5. Copper metal in magnesium sulfate solution. OBSERVATIONS: BALANCED CHEMICAL EQUATION: REACTION TYPE: OXIDATION STATES OF ELEMENTS IN REACTANTS OXIDATION STATES OF ELEMENTS IN PRODUCTS NUMBER OF ELECTRONS TRANSFERRED: Cu = Mg = Cu = Mg = SPECIES OXIDIZED SPECIES REDUCED OXIDIZING AGENT REDUCING AGENT

Metal Tested Mg2+ (MgSO4) Fe2+ (FeSO4) Cu2+ (CuSO4) No. of Reactions Mg(s) Bubble formed Bubbles formed, Mg piece browned and the FeSO4 solution darkened with the rust Bubbles formed, Mg strip turned greenish and grayish color. The solution is darkened with rust 7 Fe(s) Black coating formed Light rust formed Copper color occurred on part of pin that was exposed to the solution 3 Cu(s) No reaction occurred No reaction occurred No reaction occurred 0 For each reaction in the data table, perform the following steps: • Write the overall single-displacement reaction. • Write the half-cell reaction for oxidation. • Write the half-cell reaction for reduction. • Add the two half-cell reactions, and write the net ionic equation. • Identify the reducing agent. • Identify the oxidizing agent. After identifying the reaction, use the following format to report the information: Overall reaction: Oxidation: Reduction: Net ionic reaction: Reducing agent: Oxidizing agent:
