Silver oxide

It is a fine black or dark brown powder that is used to prepare other silver compounds.

[12] Ag2O features linear, two-coordinate Ag centers linked by tetrahedral oxides.

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 Ag2O is readily attacked by acids: where HX = HF, HCl, HBr, HI, or CF3COOH.
