3 Ag + 4 HNO 3 (cold and diluted) → 3 AgNO 3 + 2 H 2 O + NO Ag + 2 HNO 3 (hot and concentrated) → AgNO 3 + H 2 O + NO 2. The structure of silver nitrate has been examined by X-ray crystallography several times. In the common orthorhombic form stable at ordinary temperature and pressure, the silver atoms form pairs with Ag---Ag contacts of 3 ...
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. The reagent consists of a solution of silver nitrate , ammonium hydroxide and some sodium hydroxide (to maintain a basic pH of the reagent solution).

Silver nitrite is produced from the reaction between silver nitrate and an alkali nitrite, such as sodium nitrite. [3] Silver nitrite is much less soluble in water than silver nitrate, and a solution of silver nitrate will readily precipitate silver nitrite upon addition of sodium nitrite:
Some silver oxide powder.. Silver is a relatively unreactive metal, although it can form several compounds. The common oxidation states of silver are (in order of commonness): +1 (the most stable state; for example, silver nitrate, AgNO 3); +2 (highly oxidising; for example, silver(II) fluoride, AgF 2); and even very rarely +3 (extreme oxidising; for example, potassium tetrafluoroargentate(III ...
It is isostructural with Cu 2 O. It "dissolves" in solvents that degrade it. It is slightly soluble in water due to the formation of the ion Ag(OH) − 2 and possibly related hydrolysis products. [13] It is soluble in ammonia solution, producing active compound of Tollens' reagent. A slurry of Ag 2 O is readily attacked by acids: Ag 2 O + 2 HX ...
2 AgNO 3 + CoCl 2 → 2 AgCl↓ + Co(NO 3) 2. It can also be produced by the reaction of silver metal and aqua regia; however, the insolubility of silver chloride decelerates the reaction. Silver chloride is also a by-product of the Miller process, where silver metal is reacted with chlorine gas at elevated temperatures. [4]: 21 [5]
Packing of ions in solid silver sulfate. Color code: red = O, yellow = S, gray = Ag. Silver sulfate precipitates when an aqueous solution of silver nitrate is treated with sulfuric acid: 2 AgNO 3 + H 2 SO 4 → Ag 2 SO 4 + 2 HNO 3. It is purified by recrystallization from concentrated sulfuric acid, a step that expels traces of nitrate. [7]
