Potassium permanganate is an inorganic compound with the chemical formula KMnO 4.It is a purplish-black crystalline salt, which dissolves in water as K + and MnO − 4 ions to give an intensely pink to purple solution.
Potassium permanganate is an oxidizing agent. [5] The British National Formulary recommends that each 100 mg be dissolved in a liter of water before use. [3] Potassium permanganate was first made in the 1600s and came into common medical use at least as early as the 1800s. [6] It is on the World Health Organization's List of Essential Medicines ...
An issue with the city’s water pumps caused an excess of potassium permanganate to penetrate the system, turning the water bright pink and unsafe to consume.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise.
In addition, because both sodium permanganate and potassium permanganate solutions have a density greater than water's density, permanganate can travel through the contaminated area through density-driven diffusion. [3] The use of permanganate creates the byproduct MnO 2, which is naturally present in the soil and is therefore a safe byproduct. [5]
Permanganate compounds are common and strong disinfectants, used regularly to sanitize baths, toilets, and wash basins. [citation needed] It is a cheap and extremely effective compound for the task. Potassium permanganate is used as a disinfectant and water treatment additive in aquaculture. [4]

The permanganate index is an assessment of water quality. It involves the detection of oxidation by potassium permanganate in an acid medium under hot conditions. The method is to heat a sample in a boiling water-bath with a known amount of potassium permanganate and sulfuric acid for a fixed period time (10 min). Part of the permanganate will ...
