Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula P H 3, classed as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane (P2H4).

phosphine (PH3), a colourless, flammable, extremely toxic gas with a disagreeable garliclike odour. Phosphine is formed by the action of a strong base or hot water on white phosphorus or by the reaction of water with calcium phosphide (Ca 3 P 2).

2021年9月27日 · PH3 molecule, also known as phosphine, is a colourless, flammable and toxic gas compound. It is a respiratory poison and is highly dangerous to life at 50 ppm. It is a constituent of Earth’s atmosphere at significantly low and highly variable concentrations.

Phosphine (PH3) is a chemical compound which is prepared by heating phosphorous acid or also by reacting calcium phosphide with water.

PH 3 is sparingly soluble in water and soluble in organic solvents. PH 3 acts as a Lewis base by donating its lone pair of electrons when it reacts with hydrogen iodide. Under normal conditions, it is a non-combustible gas, but when heated it catches fire which results in the formation of phosphoric acid.

One of the most important chemical structure in the study of elements is Phosphine (PH3). This is a colourless gaseous substance discovered by ‘Philippe Gengembre’ in 1783 and is often confused with the study of Phosphene.

2025年2月22日 · The molecular formula of phosphene is PH3 which indicates the compound has one phosphorous atom bonding with three hydrogen atoms. To understand the structure of PH3, we should know the electronic configuration of the atoms and how many valence electrons are there in the atoms.

2023年12月20日 · Phosphine, or Phosphorous trihydride, is a colorless, flammable, highly toxic compound with the chemical formula PH3, classed as a pnictogen hydride. It is one of the most commonly used fumigants globally for the disinfestation of cereal grains, legumes, seeds, dried fruit, tree nuts, other durable food commodities, and many processed foods[1].
