Ag2o3

The compound Ag2O3 is a chemical formula that represents silver oxide. It is an inorganic compound composed of two silver ions (Ag+) and three oxide ions (O2-). The molecular weight of Ag2O3 is 303.84 g/mol.

Silver oxide is a dark brown or black powder that is insoluble in water. It is a basic oxide that reacts with acids to form salts and water. When heated, it decomposes to release oxygen gas and metallic silver.

The crystal structure of Ag2O3 is orthorhombic, which means that its unit cell has three unequal axes at right angles to each other. The lattice parameters are a = 5.761 Å, b = 8.297 Å, and c = 6.121 Å.

To prepare Ag2O3, one can react silver nitrate (AgNO3) with sodium hydroxide (NaOH) solution. This reaction produces silver oxide as a brown precipitate:

2 AgNO3 + 2 NaOH → Ag2O3 + 2 NaNO3 + H2O

Overall, Ag2O3 is a relatively rare and unstable compound. It has some uses in chemistry research, but is not widely used in industry or everyday life.
