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

因此戴维使用际上是氧化。

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

与水发生反应， 生成氧化和气。

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

以及强碱，如氧化钠和氧化。

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

顺便说一句， 水和氧根离子来自氧化溶液。

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?

他是用化学方法气吗？是用氯酸加热放出氧气，还是用氧化吸收二氧化碳气呢？

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.

其他原型使用氧化、水和热能进行一系列化学反应，最终从气中释放二氧化碳，但所有这些过程都需要额外能量和热量才能工作。
