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

以及强碱，如氢氧化钠和氢氧化钾。

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

（语）现在我要放等氢氧化钠溶液。

These chemicals are Sodium hydroxide, which is a base.

氢氧化钠，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 氢氧化钠。

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.

然后是氢氧化钠，这是我最不希出现在我最大敌人身上另一种物质， 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.

就一般用法而言，“漂白剂”一词是指普通家用漂白剂，由3-8％次氯酸钠和氢氧化钠组成。

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，火力发电厂排放细颗粒废弃物；碳纳米管，即柱状碳分子；还有两种黏合剂：硅酸钠和氢氧化钠。

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.

盐酸标准生成焓为-167. 2 kJ/mol； 对于氢氧化钠，它是每摩尔 -469. 15 kJ； 对于液态水， 它是-285. 8； 对于氯化钠， 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 pH 值。水中非常高浓度氢氧化钠 pH 值为 15，这意味着每 1 亿氢氧根离子中只有 1 个氢离子。

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标准生成焓，盐酸和氢氧化钠之间化学反应生成液态水和氯化钠。
