Ammonium sulfate (American English and international scientific usage; ammonium sulphate in British English); (NH 4) 2 SO 4, is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer.
Ammonium sulfamate is considered to be only slightly toxic to humans and other animals, making it appropriate for amateur home garden, professional and forestry uses. [5] It is generally accepted to be safe for use on plots of land that will be used for growing fruit and vegetables intended for consumption. It corrodes brass, copper, and iron.
ABC dry chemical is usually a mix of monoammonium phosphate and ammonium sulfate, the former being the active component. The mix between the two agents is usually 40–60%, 60–40%, or 90–10% depending on local standards worldwide. The USGS uses a similar mixture, called Phos Chek G75F. [2]
Ammonium is a modified form of ammonia that has an extra hydrogen atom. It is a positively charged molecular ion with the chemical formula NH + 4 or [NH 4] +.It is formed by the addition of a proton (a hydrogen nucleus) to ammonia (NH 3).
Ammonium ions are a toxic waste product of metabolism in animals. In fish and aquatic invertebrates, it is excreted directly into the water. In mammals, sharks, and amphibians, it is converted in the urea cycle to urea, which is less toxic and can be stored more efficiently.
Ammonium iron(III) sulfate, NH 4 Fe(SO 4) 2 ·12 H 2 O, or NH 4 [Fe(H 2 O) 6](SO 4) 2 ·6 H 2 O, also known as ferric ammonium sulfate (FAS) or iron alum, is a double salt in the class of alums, which consists of compounds with the general formula AB(SO 4) 2 · 12 H 2 O. [2] It has the appearance of weakly violet, octahedrical crystals.
This reaction is showing how ammonia changes into ammonium in water and generates a hydroxide ion. The form that the ammonia takes in the water also depends on the pH and temperature. Waters that are more basic have more ammonia compared to the amount of ammonium. [21] Ammonia is directly toxic to aquatic life while ammonium is not.
Ammonium lauryl sulfate (ALS) is the INCI name and common name for ammonium dodecyl sulfate (CH 3 (CH 2) 10 CH 2 OSO 3 NH 4). The anion consists of a nonpolar hydrocarbon chain and a polar sulfate end group. The combination of nonpolar and polar groups confers surfactant properties to the anion: it facilitates dissolution of both polar and non ...
