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

吸收碳酸气，要把氯化钾放在排气管中，不停地摇动玻璃管。

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

以及强碱，化钠和化钾。

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

钾与水发生反， 生成化钾和气。

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

因此戴维钾实际上是化钾。

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

顺便说一句， 水和根离子来自化钾溶液。

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?

他是化学方法获得空气吗？是氯酸钾加热放出气，还是化钾吸收二化碳气呢？

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.

其他原型化钾、水和热能进行一系列化学反，最终从空气中释放二化碳，但所有这些过程都需要额外能量和热量才能工作。
