'''碳酸银'''（[[化学式]]：[[银|Ag]]<sub>2</sub>[[碳|C]][[氧|O]]<sub>3</sub>）是米黄色或黄绿色粉末，难溶于冷水而微溶于沸水，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]]和[[二氧化碳]]，用于制取其它[[:Category:银化合物|银化合物]]。

==制备==
将[[碳酸钠]]同[[硝酸银]]反应，可以得到碳酸银。
: <chem>CO3^2- + 2 Ag+ -> Ag2CO3
</chem>

== 性质 ==
具有多数[[碳酸盐]]的通性，可以与[[酸]]反应形成银盐，二氧化碳和水：

<chem>Ag2CO3 + 2H+ -> 2 Ag+ + H2O +CO2</chem>

与过量[[氨水|浓氨水]]反应，形成[[银氨溶液|碳酸二氨合银溶液]]：

<chem>Ag2CO3 + 4 NH3*H2O-> CO3^2- + 2[Ag(NH3)2]+ + 4 H2O</chem>

==参见==
