'''氯化鎘'''是一種无色[[单斜晶系]]晶体。[[分子式]]為CdCl<sub>2</sub>，极易溶于[[水]]，微溶于[[甲醇]]、[[乙醇]]，难溶于[[丙酮]]、[[乙醚]]。

==制备==
氯化镉一般可以用[[氯化氫]]和[[鎘]]在450℃反應製成：
:<math>\ Cd+2HCl\to CdCl_2+H_2</math>
也可以通过[[乙酸镉]]的冰[[乙酸]]溶液和[[乙酰氯]]反应得到，产生的白色沉淀即为产物：<ref>朱文祥. 无机化合物制备手册. 化学工业出版社. pp 384. 【XII-26】氯化镉（cadmium chloride）</ref>
:<math rm>\ Cd(CH_3COO)_2+2CH_3COCl\to CdCl_2\downarrow+2(CH_3CO)_2O</math>
== 用途 ==
氯化鎘可用於製造[[硫化鎘]]：
:<math>\ CdCl_2+H_2S\to CdS+2HCl</math>
