It is hardly soluble in water, weak acid, weak alkali, nitric acid, cold sulfuric acid, and soluble in concentrated hydrochloric acid under heating to produce chlorine gas. . Used in the preparation of manganese salt, and also used as an oxidant, rust remover, and catalyst. Manganese dioxide is a strong oxidant in acid medium. Manganese dioxide has an octahedral structure. The oxygen atoms are on the corners of the octahedrons. The manganese atoms are in the octahedrons. The octahedrons are connected together to form a single or double chain. These chains and other chains co-top to form a tunnel structure with voids. The octahedron is either hexagonal close-packed or square close-packed. Excessive manganese entering the body can cause poisoning. It mainly damages the central nervous system, especially acute poiso
