Origin of 'NH3'
Main points about word origin
- The name 'ammonia' comes from the Latin 'sal ammoniacus,' which referred to the salt obtained from the ashes of the sacred ram of the Egyptian god Ammon.
- The prefix 'am-' in ammonia relates to ammonium, indicating its connection to nitrogen in its ionic form.
The term 'ammonia' is derived from the Latin word 'sal ammoniacus', which means salt of Ammon. This term refers to a certain type of salt obtained from the ashes of the desert plant that was originally associated with the temple of Amun near the Siwa Oasis in Libya. The chemical formula NH3 was established in the 18th century when scientists began to understand the composition of gases. In the early 19th century, ammonia began to be produced on a larger scale through various industrial processes, helping to pave the way for advances in agriculture and refrigeration methods. Ammonia's role as a nitrogen source in fertilizers has made it a crucial compound in boosting food production worldwide.
