A Few More Commonly Available Chemicals

Tungsten can be obtained from welding suppliers. 2-propanol is rubbing alcohol (isopropyl alcohol). Oxalic acid can be separated from the cleaning product Bar Keepers Friend (10% according to the MSDS). Many soluble ferrous salts can be obtained by dropping a steel nail in a solution of copper (II) [insert anion here]. They will be oxidized to ferric [insert anion here] if left exposed to the air. If you're looking for hydrofluoric acid, I've heard that it's used in the tire industry. Keep in mind that it dissolves glass.
