LiF is likly to be soluble in water because both are polar; polar solutes dissolve in polar solvents. LiF is polar; PCl3 is polar. F2, BeF2, CCl4 are not polar. answered by DrBob222. March 20, 2015. Phosphorus trichloride is an inorganic compound with the chemical formula PCl3. A colorless liquid when pure, it is an important industrial chemical, being used for the manufacture of phosphites and other organophosphorus compounds. It is toxic and reacts readily with water to release hydrogen chloride. See more Phosphorus trichloride was first prepared in 1808 by the French chemists Joseph Louis Gay-Lussac and Louis Jacques Thénard by heating calomel (Hg2Cl2) with phosphorus. Later during the same year, the English chemist See more World production exceeds one-third of a million tonnes. Phosphorus trichloride is prepared industrially by the reaction of chlorine See more The phosphorus in PCl3 is often considered to have the +3 oxidation state and the chlorine atoms are considered to be in the −1 oxidation state. Most of its reactivity is consistent with this description. Oxidation PCl3 is a precursor … See more • Phosphorus pentachloride • Phosphoryl chloride • Phosphorus trifluorodichloride See more It has a trigonal pyramidal shape. Its P NMR spectrum exhibits a singlet around +220 ppm with reference to a phosphoric acid standard. See more PCl3 is important indirectly as a precursor to PCl5, POCl3 and PSCl3, which are used in many applications, including herbicides, insecticides, plasticisers, oil additives, and flame retardants See more • 600 ppm is lethal in just a few minutes. • 25 ppm is the US NIOSH "Immediately Dangerous to Life and Health" level See more WebMagnesium fluoride does not conduct electricity when it is solid.
