This has to be one of the best loved show experiment amongst Flensburg’s chemistry students: The wax flame thrower! Since the experiment has found its way into the Flensburg laboratories, it has been shown at a number of events to great acclaim from the audience. This experiment is a relatively safe way to demonstrate combustion. It can also be used in fire safety education. If you try to extinguish burning fat or the wax on the Christmas decorations with water, you get the same effect. This is a serious risk, as your intuition will always tell you to use water to put out a fire. But in these cases, that would be the worst thing to do – as this experiment demonstrates. The combustion you can see so clearly in the video comes about through a number of steps. 1. The test tube is around 400° C hot; exposed to the cold water, it cools down rapidly and the bottom of the tube shatters. 2. Through the hole thus caused, water enters the test tube and meets the hot wax. 3. The water in the test tube evaporates immediately, greatly expands in volume and drives the liquid wax upwards and outwards. 4. The liquid wax and further gaseous components are ejected from the tube and finely disseminated. 5. The heat, fine dissemination and consequent high saturation with Oxygen mean that small, cracked particles (Hydrogen radicals) ignite in the waxen steam. 6. The flame of the radical reaction ignites the liquid part of the wax mixture. So, there is also a lot going on chemically with this experiment. Did you enjoy the video?

Nitric acid is one of the strongest acids in chemistry. Nitric acid is still used today in the mining of Gold as it dissolves common metals very effectively. It even attacks Silver but not Gold – which is why gold is so easily divided from other metals. Gold does not react with Nitric acid. The Magnesium and the Copper shavings react very quickly, releasing a reddish brown gas. The Zinc granules react after a little while in the same way. What is left in the flasks is a solution of the metal salts created by the reaction – the Copper Nitrate solution is green, the Zinc and Magnesium Nitrate solutions are yellow. Nitric acid attacks almost all common and even some of the precious metals, such as Silver and Copper. The only exceptions are the ‘noble’ metals, Gold, Platinum and Iridium. A few other metals, namely Iron, Chrome and Aluminium, are also immune because of their passivation. They form a protective oxidized layer which cannot be dissolved by the acid. Zinc also forms such a layer but it does depend on the distribution of the metal – the finer the dissemination in the acid, the stronger and quicker the reaction. Oxidation: 3 Mg ->3 Mg2+ +6e- Reduktion: 2 NO3- + 8H3O+ + 6e- -> 2 NO + 12 H2O 3 Mg + 2 NO3- + 8 H3O+ -> 3 Mg2+ 2NO + 12 H2O The released Nitrogen Monoxide is colourless but reacts immediately with the Oxygen to form brown Nitrogen Oxide. 2 NO (uncoloured) + O2 -> 2 NO2 (brown)
