Ammonium ion

Ammonium is an important ion in the fertilizer industry.

Chemical Formula: NH₄⁺

Layman's explanation: The first widespread production of ammonium compounds was in the 1890s when ammonium sulfate was produced as a by-product from coke oven gas. Ammonium ion is produced as a product of the reaction of water and ammonia. Often, ammonium salts are isomorphous. They have a similar solubility to potassium and rubidium salts, whose ions are similar in size to ammonium. The ion is most stable in the presence of a large compound with a single negative charge.

Keywords: fertilizer, isomorphous
