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

以及强碱，如钠和钾。

(mumbling) And now I'm going to put the same amount of sodium hydroxide solution.

（喃喃自语）现在我要放等量的钠溶液。

These chemicals are Sodium hydroxide, which is a base.

钠，它是一种碱 碱。

So that's like, 294 Kelvin, and now I shall add my 100 mL of sodium hydroxide.

就像是 294 开尔文，现在我要添加 100 mL 钠。

Then, there's sodium hydroxide, another substance that I wouldn't wish to be on my worst foe, although I'm glad we have it.

然后是钠，这是我最不希出现在我最大敌人身上的另一种物质， 尽管我很高兴我们拥有它。

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.

就一般法而言，“剂”一词是指普通家剂，由3-8％的次氯酸钠和微量的钠组成。

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：硅酸钠和钠。

The standard enthalpy of formation for hydrochloric acid is -167.2 kJ per mole; for sodium hydroxide it's -469.15 kJ per mole; for liquid water it's -285.8; and for sodium chloride it's -407.27.

盐酸的标准生成焓为-167. 2 kJ/mol； 对于钠，它是每摩尔 -469. 15 kJ； 对于液态水， 它是-285. 8； 对于氯钠， 它是 -407. 27。

You could technically have an even higher pH. A really high concentration of sodium hydroxide in water can have a pH of 15, which means there’s only 1 hydrogen ion for every 100 million hydroxide ions.

从技术上讲，您可以拥有更高的 pH 值。水中非常高浓度的钠的 pH 值为 15，这意味着每 1 亿根离子中只有 1 个离子。

Remember that we can look up the standard enthalpy of formation for all the products and reactants in the back of a textbook or online, the chemical reaction between hydrochloric acid and sodium hydroxide produces liquid water and sodium chloride.

请记住， 我们可以在教科书后面或网上查找所有产品和反应物的标准生成焓，盐酸和钠之间的学反应生成液态水和氯钠。
