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

因此戴维使用的实际上是氧。

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

与水发生反应， 生成氧气。

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

以及强碱，如氧钠氧。

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

顺便说一句， 水氧来自氧溶液。

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?

他是用学方法获得空气的吗？是用氯酸加热放出氧气，还是用氧吸收二氧碳气呢？

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.

其他原型使用氧、水热能进行一系列学反应，最终从空气中释放二氧碳，但所有这些过程都需要额外的能量热量才能工作。
