To absorb it, we would need to fill containers with potassium hydroxide and shake them continually.

吸收碳酸，要把氯化放在排管中，不停地摇动玻璃管。

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

以及强碱，如氢氧化钠和氢氧化。

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

与水发生反， 生成氢氧化和氢。

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

因此戴维使用的实际上是氢氧化。

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

顺便说一句， 水和氢氧根离子来自氢氧化溶液。

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?

他是用化学方法获得空的吗？是用氯酸加热放出氧，还是用氢氧化吸收二氧化碳呢？

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.

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