Make Pyrophoric Iron

You've all seen steel wool burn when a 9 volt battery is shorted across it or lit with a torch. This is a quick video showing the basic preparation of spontaneously combustible (pyrophoric) iron, which does not need any activation energy to burn. • Please take note: Oxalic acid and its salts are HIGHLY TOXIC. This is due to insoluble Calcium oxalate accumulating in the kidney and around the bones, causing excruciating pain (Fun fact: Ethylene glycol is toxic because it metabolises to oxalic acid in the body). Pyrophoric Iron is also a fire hazard that will ignite flammables. • Iron(II) oxalate is prepared by the reaction of an Iron salt with Oxalic acid, forming a yellow Iron(II) oxalate precipitant and the corresponding acid. The Fe-oxalate is filtered and dessicated. The dry powder is placed in a test tube and heated over a hot flame until the colour changes to black. The powder is then poured onto the ground (making sure it is not flammable), causing sparks. • If the powder is poured into ethanol, the ethanol will catch fire (See this on TheNaKLab's channel - I will be posting a video as well). • The Pyrophoric Iron particles, when viewed under a microscope, are determined to be from approximately 100 nm to 1 micron in size. • If you're watching my videos you might know that chemistry and electricity are quite expensive hobbies.
