Description12. Реакција на диспропорционирање.webm |
Македонски: Демонстрација на реакција на диспропорционирање. Кон купче од амониум дихромат ((NH4)2Cr2O7) се додаваат неколку капки етанол и се пали. Се забележуваат искри и формирање на продукт во вид на пепел. Ефектот прилега на ерупција на вулкан. Всушност, се работи за разложување (диспропорционирање) на амониум дихромат (портокалов) до хром(III) оксид (зелен). Реакцијата е иницирана на 180 °С, а на околу 225 °С станува самоодржувачка. Равенката на реакцијата е:
English: Demonstration of disproportionation reaction. Few drops of ethanol are added to a small pile of ammonium dichromate ((NH4)2Cr2O7) and ignited. Sparks are emitted and an ash-like product is formed. The phenomenon resembles the eruption of a volcano. Actually, this is a disproportionation reaction in which ammonium dichromate (orange) decomposes to chromium(III) oxide (green). The reaction starts at 180 °С, becoming self-sustaining at approximately 225 °С. The chemical equation is:
