What are the physical and chemical properties of Silver(1+) sulfidosilver (CAS: 21548-73-2)?

Silver(1+) sulfidosilver is a crystalline compound with a molecular weight of approximately 227.73 g/mol. It has low solubility in water but is moderately soluble in dilute acids. It exhibits limited reactivity under normal conditions but can tarnish in the presence of sulfur compounds, leading to a blackening of the surface. This compound is typically synthesized by reducing silver ions with sulfide ions in an aqueous medium.
