Silver(I) carbonate, CAS 534-16-7

Silver(I) carbonate Ag₂CO₃ is a light-sensitive inorganic silver salt, CAS 534-16-7

Substance identification

The formula Ag₂CO₃ and CAS 534-16-7 correspond to silver(I) carbonate, in which silver has an oxidation state of +1. The purity is not less than 98% per TU 6-09-3743-74. The compound is usually described as a light-yellow powder that can darken on exposure to light.

Applications and preparation

Silver carbonate is used as a laboratory reagent, a base, and a source of Ag(I) in organic and inorganic synthesis, if it is directly specified in the procedure. Its behavior depends on light, water, acidity, and particle size. The material is not a ready-made catalyst or a standard reference sample.

The sample weight is calculated based on Ag₂CO₃ and the batch purity. Operations are performed with protection from bright light and without prolonged contact with air when this is important for the method. The reagent is added in portions with control of gas evolution when interacting with acids. For quantitative analysis of silver, use a certified standard, not a calculation based on the label.

What to agree on before ordering

Request the CoA and SDS with CAS 534-16-7, purity, silver content, moisture, chloride, and impurity metals. Clarify the analysis method, appearance after storage, and light-protective packaging. For synthesis, specify limits for nitrate and alkali metals; for sensitive reactions, specify particle size distribution and insoluble residue.

Safe handling

The SDS indicates the danger of severe eye damage and high toxicity to the aquatic environment. Use a fume hood, safety goggles, gloves, and protective clothing. Avoid contact with acids outside the procedure and exposure to bright light. Do not rinse spills down the drain; collect powder, solutions, and packaging separately as silver-containing waste.
