Silver oxide Silver oxide Silver(I) oxide is the chemical compound with the formula AgO. It is a fine black or dark brown powder that is used to prepare other silver compounds. Silver oxide can be prepared by combining aqueous solutions of silver nitrate and an alkali hydroxide. This reaction does not afford appreciable amounts of silver hydroxide due to the favorable energetics for the following reaction: US patent 20050050990 describes the preparation of AgO with properties suitable for use as a fine grained conductive paste filler. AgO features linear, two-coordinate Ag centers linked by tetrahedral oxides. It is isostructural with CuO. It
Silver chromate chromate ion and the precipitate of silver chloride already formed. When approaching the endpoint, additions of silver nitrate lead to steadily slower disappearing red colorations. When the red brownish color remains (with grayish spots of silver chloride in it) the endpoint of titration is reached. This is for neutral pH. In very acidic pH, the silver chromate is soluble, and in alkaline pH the silver precipitated as hydroxide. This reaction is used, for example, to determine the chloride level in salt water pools. Silver chromate Silver chromate (AgCrO) is a brown-red monoclinic crystal and is a chemical precursor to modern
