It is composed of what sounds like a bizarre mixture: fly-ash, a fine-grained waste product from coal-fired power stations; carbon nanotubes, cylindrical molecules made of elemental carbon; and two binding agents, sodium silicate and sodium hydroxide.

煤灰，火力发电厂排放的细颗粒废弃物；碳纳米管，即柱状的碳分子；还有两种黏合剂：硅酸钠和氧化钠。

Current entering your saliva from one lead creates hydrogen gas, leaving hydroxide ions behind.

电流导线进入你的唾液中，生成气，留下氧化物。

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、水和热能进行系列化学反应，最终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。

For example, in a typical alkaline double-A battery, zinc metal reacts with hydroxide ions, changing into zinc oxide and releasing electrons at the negative terminal.

例如，常见的碱性 AA 电池中，金属与氧离子发生反应，转化为氧化，电池负极释放电子。

However, in terms of general usage, the word 'bleach' is used to refer to common household bleach, which consists of 3-8% sodium hypochlorite and trace amounts of sodium hydroxide.

就般用法而言，“漂白剂”词是指普通家用漂白剂，由3-8％的次氯酸钠和微量的氧化钠组成。

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？

But we can also use the Kw and the hydronium ion concentration to do a very simple division problem and find the hydroxide concentration.

当离子浓度上升时pH值会降低举例子，种弱酸比方说醋酸，被加到水中时。

Strong bases meanwhile, like sodium hydroxide, consume large amounts of hydrogen ions leaving the concentration very low, so they 10d to have very high pHs.

那么pH，简单地表示为负的该浓度以10为底的对数，也就是7我的这小伙伴，成为了pH标度的基础。

And that sourness dominates the flavor because while hydroxide ions can taste bitter or soapy, your tongue isn't as sensitive to them.

尝到酸味是因为虽然离子可以是苦的或者是肥皂水味的，但是舌头对这些味道不敏感。

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

吸收碳酸气，要把氯化钾放排气管中，不停地摇动玻璃管。

So the formula for Kw becomes simply the hydronium ion concentration times the hydroxide concentration.

水分子既可以释放离子，也可以接收离子。

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

因此戴维使用的钾实际上是氧化钾。

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

它们利用种名为氧化钾的化学物质来辅助产生电力。

Reactions at the negative electrode release hydroxide ions (OH–).

负极反应释放出氧根离子 (OH–)。

It will help that hydroxide cannot be stored forever. In the longer run, rising demand for lithium for energy storage, supported by green policies in America, Europe and China, could make the market even tighter.

这有助于氧化锂无法无限期储存。 长远来看，随着美国、欧洲和中国绿色政策的支持， 能源存储对锂的需求上升，可能会使市场更加紧张。

It will float on water though not for long because it is also one of the most reactive and turns rapidly into lithium hydroxide and its atoms have three electrons.

它会浮水面上，但不会很久，因为它也是最活泼的元素之，会迅速变成氧化锂，其原子有三电子。

We refine them, so we get them into the form that we need for the production -- salts for nickel, cobalt and manganese, or hydroxides for lithium.

我们对它们进行精炼，以便将其制成生产所需的形态——镍、钴和锰的盐，或者锂的氧化物。

Did you learn that neutrality, in other words a pH of 7 requires the concentration of the hydronium and the hydroxide ions to be equal?

您是否知道中性（即 pH 值为 7）要求水合离子和氧离子的浓度相等？

If you paid attention, you learned how pure water ionizes to form hydronium and hydroxide ions in reversible reactions.

也会出现0以下或是14以上的时候但那只会出现些极端条件下。

These chemicals are Sodium hydroxide, which is a base.

氧化钠，它是种碱 碱。
