silver+oxide

Silver(I) oxide is the chemical compound with the formula Ag 2 O. It is a fine black or dark brown powder that is used to prepare other silver compounds.
For commercial use, silver oxide is used as a silver-oxide battery. For organic chemistry, it is used as a mild oxidizing agent.

It is also photosensitive.

Ag2O is isostructural with Cu2O. It is therefore expected that Ag2O is insoluble in all solvents, [|[7]] except by reaction. It is also slightly soluble in aqueous solution due to the formation of the ion, Ag(OH)2– and possibly related hydrolysis products. [|[8]] It dissolves in [|ammonia] solution to give soluble derivatives.[// [|citation needed] //] A slurry of Ag2O is readily attacked by [|acids] : Ag2O + 2 HX → 2 AgX + H2O where HX = [|HF], [|HCl] , [|HBr] , or [|HI] , [|HO2CCF3]. It will also react with solutions of alkali chlorides to precipitate [|silver chloride], leaving a solution of the corresponding alkali hydroxide. [|[9]] [|[8]] Like many silver compounds, silver oxide is photosensitive. It also decomposes at temperatures above 280 °C. [|[7]
