Definition
-
Arsenic trisulfide is a chemical compound with the molecular formula As2S3. It is a yellow crystalline solid that is commonly known by its mineral name, orpiment. Arsenic trisulfide is composed of two atoms of arsenic and three atoms of sulfur, forming a 2:3 ratio in its chemical composition. It is often found in nature as a mineral deposit and has been used for various purposes throughout history.
In terms of its physical properties, arsenic trisulfide has a melting point of approximately 300 degrees Celsius and a boiling point of around 460 degrees Celsius. It is highly insoluble in water but can react with certain acids to form toxic arsine gas.
Arsenic trisulfide has a wide range of applications in different fields. It has been traditionally used as a pigment in dyes, including providing a vibrant yellow color in ceramics, paints, and textiles. Additionally, it has been employed in pyrotechnics to create yellow fireworks displays.

Etymology of ARSENIC TRISULFIDE
The word "arsenic trisulfide" is a compound noun that consists of two parts: "arsenic" and "trisulfide".
1. Arsenic: The term "arsenic" originates from the Ancient Greek word "arsenikon" or "arsenikos", meaning "yellow" or "potent". This Greek term was used to describe the element's golden-yellow appearance and its toxic nature. The Latinized form "arsenicum" was then adopted in Old French as "arsenik" and further developed into "arsenic" in English.
2. Trisulfide: "Trisulfide" is a combination of the prefix "tri-" meaning "three" and "sulfide", which comes from the Latin word "sulphur", meaning "brimstone" or "sulfur".
