Overview
Silver(I,III) oxide is an oxide of silver. It is used as part of the manufacture of silver oxide-zinc alkaline batteries. Silver is a metallic element with the chemical symbol Ag and atomic number 47. It occurs naturally in its pure, free form, as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. (L808, L809, L835)

Toxicology
Treatment
EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.
Chemistry & industry
Pharmacology
Metabolism/Metabolites
Silver and its compounds can be absorbed via inhalation, while silver compounds can also be absorbed orally and dermally. It distributes throughout the body in the blood, particularily to the liver. Insoluble silver salts are transformed into soluble silver sulfide albuminates, bind to amino or carboxyl groups in RNA, DNA, and proteins, or are reduced to metallic silver by ascorbic acid or catecholamines. Metallic silver is oxidized and may deposit in the tissues, causing arygria. Silver is eliminated primarily in the faeces. (L808)

Applications
UsesSilver(II) oxide is used to make silver oxide-zinc alkali batteries. Also, it is an oxidizing agent.
UsesSilver(II) oxide is used to make silver oxide-zinc alkali batteries. It is also used as a reagent in laboratory reactions and forms transition metal-carbene complexes. It is also used as a catalyst to prepare silver metal. It acts as an effective carbon dioxide scrubber and used in nuclear submarines, the international space station and space shuttles. Further, it is used in the manufacture of filters for gas sensors and in some infection-resistant surgical fabric materials and fibrous textile articles. In addition to this, it is used in concrete and in some swimming pools to protect the water from undesired microbes.
