The purplish-black color of solid potassium permanganate, and the intensely pink to purple color of its solutions, is caused by its permanganate anion, which gets its color from a strong charge-transfer absorption band caused by excitation of electrons from oxo ligand orbitals to empty orbitals of the manganese(VII) center.
Potassium permanganate is a crystalline solid that is typically dissolved in water before application to the contaminated site. [3] Unfortunately, the solubility of potassium permanganate is dependent on temperature. Because the temperature in the aquifer is usually less than the temperature in the area that the solution is mixed, the potassium ...
Potassium manganate is the inorganic compound with the formula K 2 MnO 4. This green-colored salt is an intermediate in the industrial synthesis of potassium permanganate (KMnO 4), a common chemical. [1] Occasionally, potassium manganate and potassium permanganate are confused, but each compound's properties are distinct.
Amateur chemistry or home chemistry is the pursuit of chemistry as a private hobby. [1] Amateur chemistry is usually done with whatever chemicals are available at disposal at the privacy of one's home.
A permanganate (/ p ər ˈ m æ ŋ ɡ ə n eɪ t, p ɜːr-/) [1] is a chemical compound with the manganate(VII) ion, MnO − 4 , the conjugate base of permanganic acid . Because the manganese atom has a +7 oxidation state , the permanganate(VII) ion is a strong oxidising agent .
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 ...

Dredging contaminated sediment in New Bedford Harbor, Massachusetts. The harbor is contaminated with polychlorinated biphenyls (PCBs).. Environmental remediation is the cleanup of hazardous substances dealing with the removal, treatment and containment of pollution or contaminants from environmental media such as soil, groundwater, sediment.
