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.

其型使用氢氧化钾、水和热能进行一系列化学反应，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和热量才能工作。

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?

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

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，如氢氧化钠和氢氧化钾。

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

因此戴维使用的钾实际上氢氧化钾。

They use a chemical called potassium hydroxide to help make power.

它们利用一种名为氢氧化钾的化学物质来辅助产生电力。

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钾溶液。

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