to make ferric chloride u need to add an oxidant to HCl before adding iron or u only get a ferrous chloride. Nitric acid is often used but i thought id try peroxide as the oxident (u can use it i beleive with sulfuric acid when making ferric sulphate). But adding peroxide turned the HCl a deep orange instantly, before any iron was even added. Any idea what was formed?
