Glycerol and potassium permanganate
Reaction of Potassium Permanganate and Glycerin is the experiment of redox reaction that consists of potassium permanganate (KMnO4), a strong oxidizing agent, and glycerol (commercially known as glycerin or glycerine) (C3H5(OH)3), an easily oxidized substance. The reation is among a number of experiments sometimes referred to as chemical volcano.
Potassium permanganate is a strong oxidizing agent and the reaction yields both flame and sparks. (Potassium permanganate (KMnO4) can react explosively if it contacts to organic or any oxidizable substances.)
Potassium permanganate (KMnO4) crystalline is put at the center of an evaporating dish. A depression is formed at the center of the pile and glycerol (C3H5(OH)3) is added to it. White smoke, a mixture of carbon dioxide gas and water vapor, is produced after that many things come up including cracking, sparking, and the violet flame, which can occur because of energy emission from the electron.
The reaction of Glycerol and Potassium Permanganate is exothermic reaction. this phenomenon can expain similarly to flame testing experiment that each electron has each energy level, but when it receive energy or heat, electrons go to the different higher level that is called the excited state, but it cannot live long so the electrons release the energy and then go back to the lower level and then energy releases as light. When the reaction is completed, it will leave the trace of the product which consists of grayish solid with green regions. In this case, the flame color of the metal Potassium Permanganate is lilac or pink color.
