碳酸银（化学式：Ag₂CO₃）是淡黄色或黄绿色粉末，微溶于水，长期光照下容易变为暗紫色或暗灰白色。加热后会分解产生氧化银，用于制取其它银化合物。

将碳酸钠同硝酸银反应，可以得到碳酸银。

CO₃ + 2 Ag → Ag₂CO₃

Silver carbonate is the chemical compound with the formula Ag₂CO₃. Silver carbonate is yellow but typical samples are grayish due to the presence of elemental silver. It is poorly soluble in water, like most transition metal carbonates.
