Documented Uses

• Used as an oxidizing agent (to convert alcohols to aldehydes and ketones) and as a biological stain; [Merck Index]
• Silver carbonate is used as a reagent in organic synthesis such as the Koenigs-Knorr reaction. It is also employed to convert alkyl bromides into alcohols. (L815)
• Carbonic acid, silver(1+) salt (1:2): ACTIVE
• 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
