Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH + 4][OH −
The amount of ammonia in ammonium salts can be estimated quantitatively by distillation of the salts with sodium (NaOH) or potassium hydroxide (KOH), the ammonia evolved being absorbed in a known volume of standard sulfuric acid and the excess of acid then determined volumetrically; or the ammonia may be absorbed in hydrochloric acid and the ...
Fumed oak choir stalls at Clonfert Cathedral, Ireland. Ammonia fuming is a wood finishing process that darkens wood and brings out the grain pattern. It consists of exposing the wood to fumes from a strong aqueous solution of ammonium hydroxide which reacts with the tannins in the wood.
Ammonium Hydroxide does in fact exist in, among other places, aqueous solutions of ammonia (NH3 plus water). The idea that water consists only of molecules of H2O nicely paired off is outdated; in fact, a glass of pure distilled water contains dissociated water (H+ and OH-) which in combination gives the charge-neutral H2O.
Ammonium hypoiodites are a class of reactive intermediates used in certain organic oxidation reactions. They consist of either ammonium itself or an alkylammonium with various substituents as cation , paired with a hypoiodite anion as the active oxidant .
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 hydroxide is commonly used but it doesn't seem to be an accurate name. There is only a small fraction of ammonium ions and hydroxide ions in NH3(aq). I think ammonia solution is more appropriate as the title. In google, "ammonium hydroxide" and "ammonia solution" have similar popularity. Both of them have more than 600,000 links.
Tollens' test for aldehyde: left side positive (silver mirror), right side negative Ball-and-stick model of the diamminesilver(I) complex. Tollens' reagent (chemical formula ()) is a chemical reagent used to distinguish between aldehydes and ketones along with some alpha-hydroxy ketones which can tautomerize into aldehydes.
