Warum tritt bei Kaliumpermanganat und Kaliumnitrat keine Redoxreaktion auf?
Es geht um Redoxreaktionen in dieser Frage und ich komme irgendwie damit nicht weiter. Im Internet könnte ich auch keine Erklärung finden. Wenn jemand vielleicht damit weiterhelfen kann, wäre ich sehr dankbar.
No reaction will occur at low temperatures. Both are quite strong oxidizing agents. The manganese should remove electrons from the oxygen (EN!). At the most when heated, nitrogen oxides could be released.
Potassium permanganate and potassium nitrate are both strong oxidizing agents and are therefore frequently used in redox reactions. However, a redox reaction does not necessarily occur when these two substances react with one another. A redox reaction presupposes that both reduction and oxidation reactions take place, electrons being transferred from one atom to another atom. In a reduction reaction, an atom takes up electrons while electrons are emitted in an oxidation reaction.
However, potassium permanganate and potassium nitrate can only function as oxidizing agents and are therefore unable to absorb electrons. If they react with one another, they can trigger a chemical reaction, but no redox reaction. If you want to achieve a redox reaction, you need to use a reducing agent capable of absorbing electrons, for example zinc, lead or carbon.
Thank you. That helped me very much!
