**硫酸銀** (Ag2SO4)，相對分子質量 311.80。密度 5.45 克 / 厘米 3。熔點 652℃，於 1085℃分解。微溶於水。溶於氨水、濃硝酸、硫酸，不溶於稀硝酸、乙醇。可用來作化學試劑。

## 製備

硫酸銀可由將硫酸銨溶液與硝酸銀溶液作用，或者由氧化銀與硫酸作用而製得。

銀和濃硫酸加熱反應，也能得到硫酸銀：

$$
{\ce {2 Ag + 2 H2SO4 -> Ag2SO4 + SO2 + 2 H2O}}
$$

在酸性環境下，硫酸銀膠體能和氯化鋇反應，生成兩個難溶沉澱：

$$
{\ce {Ag2SO4 +BaCl2 -> BaSO4 v +2AgCl v}}
$$
