Arsenic trichloride is the chemical compound with the formula AsCl3. The melting point of a solid is the temperature range at which it changes state from solid to Liquid. The boiling point of a liquid is the temperature at which the Vapor pressure of the liquid equals the environmental pressure surrounding the liquid Solubility is the characteristic Physical property referring to the ability of a given substance the Solute, to dissolve in a Solvent. Water is a common Chemical substance that is essential for the survival of all known forms of Life. Council Directive 67/548/EEC of 27 June 1967 on the approximation of laws regulations and administrative provisions relating to the classification packaging and labelling Symbolism The four divisions are typically color-coded with blue indicating level of Health Hazard, red indicating In Chemistry, the standard state of a material is its state at 1 bar (100 Kilopascals exactly A chemical compound is a substance consisting of two or more different elements chemically bonded together in a fixed proportion by Mass. Arsenic (ˈɑrsənɪk is a Chemical element that has the symbol As and Atomic number of 33 Chlorine (ˈklɔriːn from the Greek word 'χλωρóς' ( khlôros, meaning 'pale green' is the Chemical element with Atomic number 17 and This colourless liquid is a starting reagent for the synthesis of organoarsenic compounds, such as triphenylarsine. An organoarsenic compound in Organic chemistry is an Organic compound containing a Chemical bond between Arsenic and Carbon. Triphenylarsine is the Chemical compound with the formula As(C6H53
It is prepared by treatment of arsenic(III) oxide with concentrated hydrochloric acid followed by distillation:
- As2O3 + 6 HCl → 2 AsCl3 + 3 H2O
Thus, in contrast to PCl3, this compound has increased stability in the presence of acidic water. [1] It undergoes a redistribution with As2O3 and AsCl3 gives the linear polymer AsOCl. A polymer is a large Molecule ( Macromolecule) composed of repeating Structural units typically connected by Covalent Chemical bonds With chloride sources, AsCl3, forms salts containing the anion [AsCl4]−.
