Why does this oxidation result in a color change? What color change did you observe? Why do you think the temperature of the reaction increased as the reaction proceeded? Use scientific reasoning in your explanation. How would the reaction change if you added 2 g of steel wool to the acetate and reduced the iron acetate solution down to 50 mL (evaporated off 100 mL)?
