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，如氧化氧化钾。

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

钾与水发生反， 生成氧化钾气。

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

维使用的钾实际上是氧化钾。

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

顺便说一句， 水氧根离子来自氧化钾溶液。

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?

他是用化学方法获得空气的吗？是用氯酸钾加热放出氧气，还是用氧化钾吸收二氧化碳气呢？

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.

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