Etymology of AMMONIOFERRIC ALUM
The word "ammonioferric alum" is a compound composed of "ammonio", "ferric", and "alum", each of which has its own etymology.
1. "Ammonio" is derived from the Greek word "ammoniakon", which means "salt of Ammon". It refers to a compound containing ammonia or ammonium. "Ammoniakon" originates from the ancient Egyptian deity Amun (also referred to as Ammon), whose temple was located near the ancient city of Thebes (now Luxor, Egypt). Ammon was associated with the Egyptian god Amun, and the Greeks named the temple region "Ammonium", which eventually led to the term "ammonia" in chemistry.
2. "Ferric" is derived from the Latin word "ferrum", meaning "iron".
