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

吸收碳酸气，要把氯放在排气管中，不停地摇动玻璃管。

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

以及强碱，如氢氧钠和氢氧。

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

与水发生反， 生成氢氧和氢气。

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

因此戴维使用的实际上是氢氧。

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，还是用氢氧吸收二氧碳气呢？

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.

其他原型使用氢氧、水和热能进行一系列学反，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和热量才能工作。
