RXMARINE CHEMICAL TAG::
Description::
Application::
This oxide is used in silver-oxide batteries. In organic chemistry, silver oxide is used as a mild oxidizing agent. For example, it oxidizes aldehydes to carboxylic acids. Such reactions often work best when the silver oxide is prepared in situ from silver nitrate and alkali hydroxide.
Technical Specifications::
Dose::
Silver reacts readily with sulfur or hydrogen sulfide (H2S) to produce silver sulfide (Ag2S), a dark-colored compound familiar as the tarnish on silver coins and other objects. Silver sulfide also forms silver whiskers when silver electrical contacts are used in an atmosphere rich in hydrogen sulfide.
