Hypothesis: Some metals will be more reactive than other metals, due to their atomic configuration.
Materials: Copper (II) nitrate, magnesium nitrate, zinc nitrate, silver nitrate, copper grains, magnesium ribbon, zinc granules, pipets, and a 24 well plate.
Procedure: First, we added small amounts of copper (II) nitrate, magnesium nitrate, zinc nitrate, and silver nitrate to 3 seperate wells each in the 24 well plate. Thats 3 wells for each mixture. For each of the 3 wells that we gave the separate mixtures, we mixed in one with copper grains, one with a small piece of magnesium ribbon, and one with zinc granules. After each of the metals was mixed with the 3 separate solutions, we waited about 5 minutes to observe any reactions.
Copper on reacted with the silver nitrate; producing a precipitate. All of the other solutions had little to no visible reaction with the copper grains.
Magnesium had almost the opposite effect, which reacted with every solution except for the magnesium nitrate.
Zinc reacted with the copper (II) nitrate and silver nitrate solutions, but not with the zinc nitrate nor the magnesium nitrate.
Conclusion: Our hypothesis was correct to an extent. We were right in the aspect that some metals are more reactive than others. Magneium was very reactive to the solutions while copper (II) was not so very reactive. We didn't specify which metals would react more, but we got our results. In reactivity (from most to least), the metals used ranked magnesium, zinc, then copper (II).
