Phosphorus pentachloride is a greenish-yellow crystalline solid with an irritating odor. It is decomposed by water to form hydrochloric and phosphoric acid and heat. This heat may be sufficient to ignite surrounding combustible material. It is corrosive to metals and tissue. Long term exposure to low concentrations or short term exposure to high concentrations can result in adverse health effects from inhalation.
The chemical element barium is a heavy, soft, silvery-white metal that, like the element chlorine, always occurs combined in nature. Due to their reactivity, barium and chlorine form compounds naturally. The most common form of barium in nature is the salt barium sulfate, BaSO4, also known as the mineral barite. It is also the chief ore of barium. Barium chloride, another barium salt, can be manufactured by reacting barium sulfate with hydrochloric acid, HCl.
