* Fixed Composition: It always has a fixed ratio of silver (Ag) to carbonate (CO₃) ions. The ratio is 2:1, meaning for every two silver ions, there is one carbonate ion.
* Uniform Properties: All samples of pure silver carbonate will have the same physical and chemical properties. This includes color (white), melting point, density, and reactivity.
* Single Substance: Silver carbonate is made up of only one type of molecule, Ag₂CO₃, and not a mixture of different substances.
In contrast, a mixture would contain different substances that are not chemically bonded together, and their proportions could vary.
Therefore, due to its fixed composition, uniform properties, and single substance nature, silver carbonate is classified as a pure compound.
