'''鉻酸銀'''，其化學式為Ag<sub>2</sub>CrO<sub>4</sub>，密度為5.625g/cm<sup>3</sup>。

== 性質 ==
紅棕色，呈結晶或粉末狀。可溶解在酸(H<sup>+</sup>)、[[鹼金屬]][[铬酸盐]]溶液（例如Na<sub>2</sub>CrO<sub>4</sub>）、[[氰化鉀]]溶液(KCN)、[[氨水]]（NH<sub>3</sub>·H<sub>2</sub>O），微溶於水。<ref>Pradyot Patnaik. ''Handbook of Inorganic Chemicals''. McGraw-Hill, 2002, ISBN 0070494398</ref>

== 製備 ==
[[鉻酸鉀]]溶液與[[硝酸銀]]溶液，經反應過後生成沉澱，再以[[濾紙]]過濾而得。
:<math>K_2 CrO_4 + 2AgNO_3 \rightarrow Ag_2 CrO_4 + 2KNO_3</math>

== 用途 ==
作為化學分析之試劑、有機合成之[[催化劑]]、[[電鍍]]或是[[鹵化物]]莫氏法確定[[滴定]]終點的[[指示劑]]。
