The sediment of a lake-its muddy bottom layer-contains relatively high concentrations of nitrogen and phosphorus. These can be released to water, particularly under conditions of low oxygen concentrations. The nutrients in the sediment come from the past settling of algae and dead organic matter.
Potassium permanganate is an inorganic chemical compound with the chemical formula KMnO 4. It is a salt consisting of K+ and MnOâ 4 ions. Formerly known as permanganate of potash or Condy's crystals, it is a strong oxidizing agent.It dissolves in water to give intensely pink or purple solutions, the evaporation of which leaves prismatic purplish-black glistening crystals.In 2000, worldwide production was estimated at 30,000 tonnes.Using sodium hydroxide the end product is not sodium manganate but an Mn(V) compound which is one reason the potassium permanganate is more commonly used than sodium permanganate. Furthermore the potassium salt crystallizes better).
Save. Potassium permanganate is an inorganic chemical used for several household and industrial purposes. It is a common oxidizing reagent that can be used to remove odors and metals from water systems. Its chemical formula is KMnO4, which consists of the K+ potassium ion combined with the MnO4 manganese compound.ommon Household Uses. Potassium permanganate is a mild disinfectant. It is used to treat fungal infections like athlete's foot and is also used for other skin maladies like eczema. The salt is a preservative that florists can use as a preservative to extent the life of fresh cut flowers.
