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).

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.

Phosphorus trihydride (PH3) – most commonly known as phosphine – is mainly used for fumigation applications because of biocide properties – required for international transport. Phosphine is also industrially released while producing acetylene, during metals de-rusting process with phosphoric acid or in metal treatment plants with phosphides.

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.
