Iron Oxide is an inorganic compound. It is a very useful chemical compound which is made up of iron and oxygen. It occurs by the oxidation of iron. Its chemical formula is Fe2O3. Chemical Appearance Iron Oxide has the appearance of a red brown solid. It mostly comes in the powdered form. It is an odourless compound. It is insoluble in water. Chemical Applications and Strengths Iron Oxide is an extremely efficient chemical compound and therefore, has many commercial applications. Its main applications and strengths are: Iron Oxide is most popularly used as feedstock in the iron and steel industries for the mass production of iron, steel, and other alloys. The fine powder of iron oxide is known as rouge and it is used to polish metallic jewellery and lenses. It is also used as a cosmetic. Rouge cuts more slowly than modern polishes but it is still widely used because it gives a superior finish. CAS Number:1309-37-1 HS Code:28211010

Chemical appearance: Copper (II) sulfate pentahydrate is a blue crystalline solid. It is not combustible and has a strong, nauseating metallic taste. However, it is odorless. When dehydrated, it turns white. Chemical application and strengths: Copper sulfate is made by treating copper with hot concentrated sulfuric acid. The crystal combines with other elements for the preparation of different compounds. In its pure nature, it is used as fungicide. It is also mixed with sodium hydroxide to control fungus in melons and grapes. Copper sulfate is used in swimming pools as an algaecide. It is also used for the control of invasive plants in the pools and controls roots that may have punctured the piping system. Fish farmers use it to kill off the invasive types of snails in aquariums. However, its use in the aquarium is highly controlled, as it is toxic to fish in high quantities.
