So the potash that Davy was using was actually potassium hydroxide.

因此戴维使用的钾实际上是化钾。

Potassium reacts with water, forming potassium hydroxide and hydrogen gas.

钾与水发生反应， 生成化钾。

As well as strong bases, like sodium and potassium hydroxide.

以及强碱，如化钠化钾。

The water and hydroxide ions, by the way, come from a solution of potassium hydroxide.

顺便说一句， 水离子来自化钾溶液。

Did he obtain air using chemical methods, releasing the oxygen contained in potassium chlorate by heating it, meanwhile absorbing the carbon dioxide with potassium hydroxide?

他是用化学方法获得空的吗？是用氯酸钾加热放出，还是用化钾吸收二化碳呢？

Other prototypes use potassium hydroxide, water and heat energy to go through a series of chemical reactions that eventually release CO2 out of the air, but all of these processes require extra energy and heat in order to work.

其他原型使用化钾、水热能进行一系列化学反应，最终从空中释放二化碳，但所有这些过程都需要额外的能量热量才能工作。
