KMnO4 density is the concentration of potassium permanganate in a solution, as measured by volume of water. It is used as a disinfectant and oxidizing agent. It is also used in chemical analysis as a test for unsaturation of organic compounds, often referred to as Baeyer’s reagent.
Potassium permanganate is a strong oxidizer that reacts strongly with certain organic compounds. It can cause severe eye and skin irritation if swallowed or inhaled, and may even cause fires.
Uses for KMnO4 (Korea):
In a laboratory, it is often used as an oxidizing agent in the preparation of acetone, acetic acid, methanol, pyridine, and ethanol. It has a slightly acid or bitter taste and is soluble in a variety of solvents.
When heated, it undergoes thermal decomposition and forms manganese dioxide which releases oxygen gas. The oxidation reaction depends on the pH and other conditions such as temperature, concentration of the reactants, and other additives.
It is a powerful oxidizing agent that can be used for sterilizing and purifying water, as well as in many other applications. The compound can be reacted with concentrated hydrochloric acid to produce chlorine.
The oxidation reaction can be accelerated by the heating of organic matter or in alkaline solutions such as sodium hydroxide or potassium hydroxide. In addition, KMnO4 can be used to kill bacterial propagules and spores, particularly when diluted to a low concentration.
Despite its many uses, potassium permanganate is an air pollutant and is listed as a hazardous air pollutant (HAP) under the Clean Air Act. EPA must set and phase in performance based standards for air emission sources that emit one or more of the listed pollutants.
