About Phosphine
- It is a chemical compound made of one phosphorus atom and three hydrogen atoms.
- Formation: Phosphine on Earth is developed naturally by bacteria that live in very low-oxygen environments.
- To produce phosphine, Earth bacteria take up phosphate from minerals or biological material and add hydrogen.
- It is also found in the atmospheres of Jupiter and Saturn.
- It is also called hydrogen phosphide.
- Uses of Phosphine: It is used in semiconductor and plastics industries, in the production of a flame retardant, and as a pesticide in stored grain.
Properties of Phosphine
- It is a colourless, flammable, extremely toxic gas with a disagreeable garlic like odour.
- It is slightly soluble in water.
- It is formed by the action of a strong base or hot water on white phosphorus or by the reaction of water with calcium phosphide (Ca3P2).
- It is structurally similar to ammonia (NH3), but phosphine is a much poorer solvent than ammonia and is much less soluble in water.
