"Sal Ammoniac" is a word that refers to ammonium chloride, a white crystalline substance used in various industrial and medical applications. The spelling of "Sal Ammoniac" is derived from its Latin origin, Sāl ammōniacus. The word is pronounced /sæl əˈmoʊniæk/ in IPA phonetic transcription, with the first syllable pronounced "sal" and the second syllable pronounced "ammoniac."

Sal Ammoniac, also known as ammonium chloride, is a chemical compound with the molecular formula NH4Cl. It is a white crystalline substance that is highly soluble in water and has a strong, pungent odor. Historically, it was produced from the burning of camel dung in Egypt and used in various applications.
In terms of its chemical composition, sal ammoniac consists of ammonium cations (NH4+) and chloride anions (Cl-). It is primarily sourced from volcanic regions, where it is found as a mineral or deposited as a volcanic sublimate.
Sal ammoniac has numerous applications in various industries. It is commonly used as a flux in soldering, as it helps remove oxides from the metal surfaces being joined. In the manufacturing of textiles, it is used as a dye-fixing agent. It is also employed in the leather industry for tanning and in the production of dry cell batteries.
Furthermore, sal ammoniac has applications in laboratory settings. It is used as a source of ammonia gas, as well as a reagent for chemical reactions. It is also utilized in the calibration and maintenance of pH meters.
Despite its many uses, sal ammoniac should be handled with caution due to its corrosive nature. It can cause irritation to the skin, eyes, and respiratory system. Therefore, appropriate safety precautions should be taken when using or handling this compound.

The word "Sal Ammoniac" has an interesting etymology. It can be traced back to the ancient Egyptians, who discovered a white mineral substance near the temple of Amun in the Libyan desert. This substance was named "Ammoniac salt" or "salt of Amun" after the Egyptian god Amun.
The Greek philosopher and historian Herodotus later encountered this substance during his travels to Egypt in the 5th century BCE. He wrote about its production and called it "ammoniakon sal" in Greek, meaning "salt of Ammon". The Greek word "sal" refers to salt in general, and "ammoniakon" denotes its association with Amun.
From Greek, the term traveled to Latin as "sal ammoniacus" or "ammoniacum sal". The Romans commonly used it to describe the same mineral substance.
