Sodium hydroxide and Hypochlorous acid from bleach neutralize these proteins.

漂白剂中亚氯酸会中和这些。

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

（喃喃自语）现在要放等量氢氧化钠溶液。

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

就像是 294 开尔文，现在要添加 100 mL 氢氧化钠。

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，简单地表示为负该浓度以10为底对数，也就是7这个小伙伴，成为了pH标度基础。

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，这是最不希望出现在最大敌人身上另一种物质， 很高兴们拥有它。

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％次氯酸钠和微量氢氧化钠组成。

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，即柱状碳分子；还有两种黏剂：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， 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。
