What is the chemical Name of H3P(aq)
The Correct Answer and Explanation is :
The chemical formula H₃P(aq) represents phosphine, which is commonly written as PH₃ in its molecular form. The “(aq)” indicates that the phosphine is in aqueous solution, meaning it is dissolved in water.
Explanation:
Phosphine, PH₃, is a chemical compound composed of one phosphorus (P) atom and three hydrogen (H) atoms. It is a colorless, flammable gas with a foul odor, often described as smelling like rotten fish. Phosphine is structurally similar to ammonia (NH₃), where phosphorus replaces nitrogen as the central atom. Like ammonia, phosphine is a weak base but is more unstable and hazardous.
Phosphine is produced industrially primarily through the reaction of white phosphorus with a base like sodium hydroxide:
[
P_4 + 4 NaOH + 2 H_2O \rightarrow 2 PH_3 + 2 Na_2HPO_4
]
In aqueous solution (indicated by “(aq)”), phosphine may dissolve in water to a limited extent, where it can react with water to form phosphonium ions (PH₄⁺), though this reaction is not very common in dilute solutions.
Phosphine is of particular interest in the context of chemistry and industry because of its uses as a fumigant in pest control and as a precursor in the production of phosphorous-containing compounds. It also has applications in the semiconductor industry and as a reducing agent in various chemical reactions.
Despite its utility, phosphine is highly toxic and poses significant health risks if inhaled. Symptoms of poisoning can include nausea, vomiting, difficulty breathing, and even death in extreme cases. As such, its handling requires extreme caution, especially in confined spaces.
In summary, the chemical name for H₃P(aq) is phosphine. It is a toxic, flammable gas with applications in fumigation and industrial processes.
