A sample of pure tin metal (which forms Sn 2+ nitrate. that would be present at the equivalence point. ions) is added to 200 mL of a 1.5 M solution of copper (II) a. Identify and write out both the oxidation and reduction half reactions (2 pts) b. Use the balanced half reaction equations to determine the overall net ionic equation for the reaction. (1 pt) c. Identify any spectator ions in the reaction (1 pt) d. Determine the maximum mass of copper metal that can be collected after the reaction if the tin metal has a mass of 30.0 g. (1 pt)
