Silver ( I, III ) oxide is an inorganic chemical compound of the silver from the group of oxides.

Production and representation

Silver ( I, III ) oxide can be obtained in alkaline medium at 90 ° C by persulfate oxidation of silver (I ) oxide.

Properties

Silver (I, III ) oxide is a light-sensitive dark gray odorless solid which reacts with water. He has strong oxidizing, is soluble in nitric acid and decomposes under the action of sulfuric acid to release of oxygen. It has a monoclinic crystal structure with space group P21 / c ( a = 585.2 pm, b = 347.8 pm, c = 549.5 pm, a = 107.5 °, Z = 2).

Use

Silver (I, III ) oxide is used in organic chemistry for the conversion of benzyl halides directly into benzyl ethers. It also serves as a surface catalyst for the epoxidation of alkenes. It is also used in the production of silver-zinc accumulators.
