ARSENIC PENTACHLORIDE Meaning and Definition

  1. Arsenic pentachloride is a chemical compound composed of one atom of arsenic and five atoms of chlorine, with a chemical formula AsCl5. It is classified as a covalent compound due to the sharing of electrons between the arsenic and chlorine atoms. Arsenic pentachloride is a yellowish, volatile, and highly toxic substance that exists as a crystalline solid under normal conditions.

    This compound is mainly used in chemical synthesis and as a catalyst in organic reactions. It is particularly employed in the acylation of alcohols and amines, where it acts as a Lewis acid to facilitate the reaction. Arsenic pentachloride has a strong affinity for oxygen and water, reacting vigorously with both to produce arsenic compounds, hydrochloric acid, and heat. As a result, it should be handled with extreme caution and stored in a dry and well-ventilated area away from moisture and incompatible substances.

    Exposure to arsenic pentachloride can be dangerous, causing severe irritation and burns to the skin, eyes, and respiratory system. Inhalation or ingestion of this compound can lead to acute poisoning, characterized by symptoms such as nausea, abdominal pain, vomiting, and difficulty breathing. Prolonged or repeated exposure may result in chronic arsenic poisoning, leading to serious health complications including cancer, neurological disorders, and organ damage.

    Due to its high toxicity and hazardous nature, strict safety protocols and protective equipment should be used when handling or working with arsenic pentachloride to minimize the risk of accidents and adverse health effects.

Etymology of ARSENIC PENTACHLORIDE

The word "arsenic" can be traced back to the Old French word "arsenic" and the Latin word "arsenicum". These terms derived from the Arabic word "زرنيخ" (zarnikh), which refers to the yellow orpiment mineral that was confused with arsenic sulfide in ancient times.

The term "pentachloride" consists of two elements. "Penta-" is a prefix derived from the Greek word "penta", meaning "five", while "chloride" comes from the Latin word "chloridum", derived from the Greek word "khloros" meaning "a pale green color". Chlōros originally denoted "greenish-yellow" and was later associated with chlorine due to its color.

Therefore, "arsenic pentachloride" refers to a compound that consists of arsenic combined with five chlorine atoms.
