I am studying oxidation reactions and I need some experiments that I can do to demonstrate oxidationI already have the exploding gummy bear using potassium chlorate.what other experiments can I do?The chemicals used don\'t matter, legal or illegal.I have access to almost any chemical I would needHelp is greatly appreciated.Yankeefed said: The chemicals used don\'t matter, legal or illegal.I have access to almost any chemical I would needAren\'t you the dangerous pyromaniacWell, here is a nice tame redox reaction that will make you popular with your mother, not to mention the fire marshal and the chief of policeWrap tarnished silverware in aluminum foil and submerge in water with table salt (NaCl) dissolved itDo this in something that you can heat over the stoveGently heat the water and aluminum wrapped silverware for a few minutesWhen you unwrap the silverware the tarnish will be gone and the aluminum will be blackWhy? Silver tarnish is silver sulfide3Ag2S(s) + 2Al - Al2S3(s) + 6Ag If you omit the NaCl it won\'t workThe aluminum foil has a thin coating of Al2O3 that reacts with chloride ion to expose fresh Al metal to react with the silver tarnish.Other related question
