Etymology of AMMONIUM PERSULFATE

The word "ammonium" has its origin from the Latin word "ammoniaca", which refers to the gum resin obtained from the Egyptian plant called Jupiter's beard or Syrian thorn. This resin was thought to contain ammonia and was associated with the temple of Jupiter Ammon in ancient Libya. The term "ammonium" was later used to represent a compound in which the nitrogen atom is combined with hydrogen atoms to form a positive ion.

On the other hand, "persulfate" is a combination of the prefix "per-" and the word "sulfate". The prefix "per-" in chemistry implies the highest possible oxidation state of an element. "Sulfate" is derived from the Latin word "sulphur", which means sulfur. Thus, "persulfate" represents a compound that contains the highest oxidation state of sulfur.
