'''乙酸钾'''是[[乙酸]]的[[钾]]盐，[[化学式]]为{{化學式|碳|氫|3|碳|氧|氧|鉀|link=}}.

== 制备 ==
乙酸钾可由[[氢氧化钾]]或[[碳酸钾]]与[[乙酸]]发生酸碱[[中和反应]]制备：

: <chem>2CH3COOH + K2CO3 ->CH3COOK + CO2 +H2O</chem>

== 应用 ==
乙酸钾的应用有：
*可用作[[防冰物质]]，取代[[氯化钙]]和[[氯化镁]]之类的[[氯化物]]。它对土壤的侵蚀作用和腐蚀性更小，尤其适用于机场跑道除冰，但价格较昂贵。

*食品添加剂（防腐及控制酸度）
*[[灭火器]]的组分
*用于治疗[[糖尿病酮症酸中毒]]，原理是呈碱性且可以与[[碳酸氢盐]]反应
*[[分子生物学]]中用于沉淀[[十二烷基硫酸钠]]
*用在[[乙醇]]沉淀DNA中
*用于保存、固定生物组织，与[[甲醛]]连用<ref>{{Cite web |url=http://www.uqtr.ca/plast-journal/vol8/Ulmer_7a10.pdf |title=Dale Ulmer, "Fixation.

== 安全 ==
储存时需要避免的条件有：[[潮湿]]、[[加热]]、[[火源]]、[[自燃]]物体及强[[氧化剂]]。
