Pentoksidi
Pentoksidi refers to a chemical compound containing five oxygen atoms. The most common and well-known pentoxide is phosphorus pentoxide, with the chemical formula P2O5. This white, crystalline solid is a powerful dehydrating agent and is often used in chemical synthesis to remove water. It reacts vigorously with water to form phosphoric acid. Other elements can also form pentoxides, such as arsenic pentoxide (As2O5) and vanadium pentoxide (V2O5). Vanadium pentoxide is a key catalyst in the industrial production of sulfuric acid. The properties and reactivity of pentoxides vary significantly depending on the central element. They are generally acidic oxides, except for some less common ones.
