In the colorimetric (color producing) assay for iron used in this lab; potassium thiocyanate, KSCN, is added to produce a deep red colored precipitate. The lab outline suggests that H2O2 may be added to enhance the color. Write a balanced chemical equation showing the function of the peroxide. In your equation identify the oxidizing agent and the reducing agent.
Write a balanced chemical equation that describes the reaction of iron metal with HCl. Identify the oxidizing and reducing agents in your balanced equation.
