性质与稳定性

Properties and stability

1、易潮解。暴露于空气中时，易吸收二氧化碳和水分，逐渐变成碳酸钾。易溶于水，溶解时放出大量溶解热，有很强的吸水性，在空气中能吸收水分而溶解，并吸收二氧化碳逐渐变成碳酸钾。溶于乙醇，微溶于醚。有很强的碱性和腐蚀性，其性质与烧碱相似。能引起灼伤。易于吸收空气中的水分和CO2。

1. Deliquescent. When exposed to the air, it is easy to absorb carbon dioxide and water, and gradually turns into potassium carbonate. It is easy to dissolve in water, emits a lot of heat of dissolution when dissolving, and has strong water absorption. It can absorb water and dissolve in the air, and absorb carbon dioxide to gradually turn into potassium carbonate. Soluble in ethanol, slightly soluble in ether. It is highly alkaline and corrosive, and its properties are similar to caustic soda. Can cause burns. Easy to absorb moisture and CO2 in the air.
