Potassium permanganate to potassium manganate (oxidation state +6) and manganese dioxide (oxidation state +4). Oxygen gas is also liberated. Potassium permanganate poses risks as an oxidizer. Contact with skin will result in a long lasting pinkish/purple stain. Potassium permanganate Potassium permanganate is an inorganic chemical compound and medication. As a medication it is used for cleaning wounds and dermatitis. It has the chemical formula KMnO and is a salt consisting of K and ions. 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,
Potassium polyacrylate with less water and fewer inputs. As a soil amendment, potassium polyacrylate can improve the soil water holding capacity. Potassium polyacrylate Potassium polyacrylate is a potassium salt of polyacrylic acid with the chemical formula [−CH−CH(COK)−] As a type of superabsorbent polymer, it can absorb hundreds times its original weight in purified water. Different from sodium polyacrylate, potassium polyacrylate can be used as water retaining agent in agriculture and won't cause soil salinization. As a type of superabsorbent polymer for plants (Ag-SAP), potassium polyacrylate can increase moisture availability to plants. It mixes with soil to increase the soil’s capacity for holding
