Heavy Metals: Oxidation and Metal Staining

Water is the universal solvent, and can eventually dissolve just about anything. Yes, this includes metal minerals like calcium and magnesium, and it also includes heavy metals like copper, iron, manganese and silver. Unlike minerals (calcium and magnesium), heavy metals are oxidants, which means they get oxidized in the presence of chlorine.
