KOH permanganate density g ml
Potassium permanganate, also known as potassium manganate, gray manganese oxide and PP powder, is an odorless, purple to magenta crystalline solid or needles. It is used in solutions as a disinfectant, topical antibacterial agent; deodorizer, bleaching agent; and in air and water purification.
Physical properties
KMnO4 is slightly soluble in water, and a small amount of solution dissolves in acetone, acetic acid, pyridine and methanol. It decomposes in ethanol and organic solvents to produce manganese dioxide and oxygen.
Chemical properties
KWnO4 is a strong oxidant, and can react with many inorganic compounds. It can oxidise carbon atoms that have double bonds in weak alkaline or neutral medium. It can also oxidise aldehydes, alcohols and sugars to acids or carboxylic acids.
Reactions
KSnO4 has a number of reactions with common compounds such as ethene, benzene and formaldehyde. It also reacts with methyl cyanide, a component of most photographic flash powders, to provide ethylene glycol as a by-product.
Effects on health
KMnO4 can cause irritation in the throat and nose when inhaled. It can be harmful to pregnant women.
Ingestion can cause diarrhea, vomiting and abdominal pain. It can also cause kidney & liver damage.
Uses
KKnO4 is a very popular water treatment agent that removes iron and hydrogen sulfide, controls zebra mussels and rust in pipework. It is also used to treat fish diseases and parasites.
It is used in chemistry labs and survival kits for a variety of purposes, such as destroying pests in a garden or aquarium. It is also a fire starter and is used as a propellant in rockets.
