One common method for filtering out phosphine gas is to use a glass fiber filter with a pore size small enough to capture the gas molecules. Activated carbon filters can also be effective in removing phosphine from air or gas streams. Additionally, chemical scrubbers using materials like potassium permanganate or sodium hypochlorite can be used to react with and remove phosphine gas.

Phosphine (PH3) is a stronger reducing agent than ammonia (NH3) because phosphorus is less electronegative than nitrogen, making it easier for phosphorus to donate electrons. This leads to phosphine being more readily oxidized and exhibiting stronger reducing properties compared to ammonia. Additionally, phosphine has a weaker P-H bond compared to the N-H bond in ammonia, which contributes to its stronger reducing ability.

You might think trigonal planar, but it's actually trigonal pyramidal. Remember that phosphorus (like nitrogen) ends up with a lone pair when it bonds to three things covalently. That lone pair causes a lot of distortion and you end up with the pyramid shape.

Phosphine is a gas at room temperature because its molecules are relatively small and have weak intermolecular forces. This results in low binding energy between the molecules, allowing them to move freely and escape into the gas phase easily.

Phosphine (spelled with 's' in 4th position) is phosphorus trihydride, PH3 (compare NH3).
It is a colorless, flammable, toxic gas.
Pure phosphine is odourless, but technical grade samples have a highly unpleasant odor like garlic or rotting fish, due to the presence of substituted phosphine and diphosphine (P2H4)
Phosgene is carbonyl dichloride, COCl2,
This very toxic, colorless gas.
It gained infamy as a chemical weapon duringWorld War I. In low concentrations, its odor resembles freshly cut hay or grass.

Phosphine can form through several methods. One common way is through the reaction of a metal phosphide with a strong acid, such as hydrochloric acid. Another way is through the biological process in anaerobic environments by certain types of bacteria that produce phosphine as a metabolic byproduct.

The spontaneous combustion of phosphine is technically used in Holme's
signals. Containers containing calcium carbide and calcium phosphide are
pierced and thrown in the sea when the gases evolved burn and serve as a
signal. It is also used in smoke screens.
Containers which have a perforated bottom and a hole at the top are filed with calcium phosphide and calcium carbide. These are thrown into the sea. Waterebters the containersthrough the bottom and and reacts to give acetylene and phosphine. Phosphine gets ignited spontaneously as it comes in contact with air and also ignites acetylene. Thus a bright red flame is produced which is accompanied by huge smoke due to the burning of phosphine. This serves as a signal to the approaching ships.
1 answer
Ammonia is a stronger base than phosphine because the nitrogen in ammonia is more electronegative than phosphorus in phosphine, leading to a higher electron density on the nitrogen atom in ammonia. This extra electron density makes the lone pair on ammonia more available to accept protons, resulting in stronger basicity.

Phosphine is more basic than ammonia because phosphorus is less electronegative than nitrogen, allowing the lone pair of electrons on phosphine to be more available for donation. Additionally, the larger size of phosphorus in phosphine leads to weaker P-H bonds, making it easier for the lone pair to be donated.

An aminodiphosphine is a compound containing an amino group and two phosphine groups, especially such a compound used as a chelating agent.
1 answer
Phosphine, or PH3, has (quite obviously) three hydrogen atoms singly bonded to a phosphorus atom. Because of the presence of a lone pair of electrons, the phosphorus atom is sp3 hybridized, and the electron orbitals adopt a tetrahedral configuration. As mentioned earlier, one orbital is non-bonding and thus the molecular shape is trigonal pyramidal.

It contains a lone pair of electrons. Hence, it can donate it thereby ,its a base. The tendency to donate the electron pairs can determine the basicity of a base. Therefore, PF3 is less basic than PH3.

Ammonia is more soluble in water than phosphine because ammonia can form hydrogen bonds with water molecules due to its ability to donate a lone pair of electrons, increasing its solubility. Phosphine, on the other hand, lacks the ability to form hydrogen bonds with water and therefore is less soluble in comparison.

When white phosphorus is heated with concentrated sodium hydroxide, a chemical reaction occurs called the Berthelot's or Cannizzaro's reaction. This reaction results in the formation of phosphine gas (PH3) and sodium hypophosphite (NaH2PO2). This reaction is highly exothermic and must be conducted with caution due to the toxic and flammable nature of phosphine gas.
