Silver(Ii) Oxide

Silver(II) oxide, also known as silver peroxide, is a chemical compound with the formula AgO. It is an unstable and rare oxide of silver, as most silver compounds are either silver(I) or silver(III) complexes.

Silver(II) oxide can be prepared by reacting silver nitrate with hydrogen peroxide in alkaline solution. It can also be obtained by reacting silver(I) oxide with ozone gas.

AgNO3 + H2O2 + NaOH → AgO + NaNO3 + 2H2O

Ag2O + O3 → 2AgO + O2

Silver(II) oxide is a dark brown to black powder that is insoluble in water and organic solvents. It decomposes easily, especially when exposed to light, heat, or moisture, releasing oxygen gas and forming silver metal.

2AgO → 2Ag + O2

Due to its instability and rarity, silver(II) oxide has limited practical applications. However, it has been used in some organic reactions as an oxidizing agent, and in the preparation of other silver compounds.
