Sodium hydroxide and Hypochlorous acid from bleach neutralize these proteins.

漂白剂中亚氯会中和这些。

The sodium hydride could be combined with water to produce sodium hydroxide and hydrogen gas.

氢化钠可以与水结合产生氢氧化钠和氢气。

(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，现在我要添加 100 mL 氢氧化钠。

So they make a salt of benzoic acid by reacting it with sodium hydroxide — aka lye or caustic soda — to make sodium benzoate.

所以他们通过与氢氧化钠——也就是碱液或苛性钠——反应生成苯甲。

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，简单地表为负该浓度以10为数，也就是7我这个小伙伴，成为了pH标度基础。

So for example, sodium hydroxide releases about 250 kilocalories of energy for every mole, which is about six hundred billion trillion molecules.

因此， 例如，氢氧化钠每摩尔释放约 250 大卡能量， 即约 6000 亿兆分子。

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，这是我最不希望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％次氯钠和微量氢氧化钠组成。

So when sodium hydroxide feels slippery to you, it's actually the sodium hydroxide doing chemistry with the oils in your skin to form a kind of soap.

因此，当您觉得氢氧化钠很滑时，实际上是氢氧化钠与您皮肤中油脂发生化学反应， 形成一种肥皂。

Bases like sodium hydroxide, or lye, are combined with fatty acids in vegetable oil or animal fat to produce sodium salts, which help water lift grease away from your skin.

氢氧化钠或碱液等碱与植物油或动物脂肪中脂肪结合生成钠，有助于水将油脂从皮肤上去除。

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.

标准生成焓为-167. 2 kJ/mol； 于氢氧化钠，它是每摩尔 -469. 15 kJ； 于液态水， 它是-285. 8； 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，和氢氧化钠之间化学反应生成液态水和氯化钠。
