Ammonium chloride is an inorganic chemical compound with the chemical formula N H 4 Cl, also written as [NH 4]Cl. It is an ammonium salt of hydrogen chloride.
Quaternary ammonium cation. The R groups may be the same or different alkyl or aryl groups. Also, the R groups may be connected. In organic chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure [NR 4] +, where R is an alkyl group, an aryl group [1] or organyl group.
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
The ammonium salts of nitrate and especially perchlorate are highly explosive, in these cases, ammonium is the reducing agent. In an unusual process, ammonium ions form an amalgam. Such species are prepared by the addition of sodium amalgam to a solution of ammonium chloride. [3] This amalgam eventually decomposes to release ammonia and ...

For example, in ammonium chloride solution, NH + 4 is the main influence for acidic solution. It has greater K a value compared to that of water molecules; K a of NH + 4 is 5.6 × 10 −10, and K w of H 2 O is 1.0 × 10 −14. This ensures its deprotonation when reacting with water, and is responsible for the pH below 7 at room temperature.
More than 800 people have lost their lives in jail since July 13, 2015 but few details are publicly released. Huffington Post is compiling a database of every person who died until July 13, 2016 to shed light on how they passed.
This substance is commonly called "commercial ammonium fluoride". The word "neutral" is sometimes added to "ammonium fluoride" to represent the neutral salt [NH 4]F as opposed to the "acid salt" (NH 4 HF 2). The acid salt is usually used in preference to the neutral salt in the etching of glass and related silicates. This property is shared ...
