Silver Oxide Colour

Silver oxide (Ag2O) is a chemical compound that appears as a dark brown to black powder. However, its color may vary depending on the particle size and method of preparation.

In its pure form, silver oxide has a brownish-black color due to the presence of small amounts of impurities such as silver metal and oxygen vacancies. When exposed to air and light, it can gradually decompose into metallic silver and oxygen, leading to a change in color over time.

In some cases, silver oxide may appear as a grayish-white powder if it is synthesized using specific methods or treated with reducing agents that convert it to metallic silver. In general, the color of silver oxide is primarily determined by its chemical composition and physical properties rather than any inherent optical properties.
