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：硅酸和氢。

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％次氯酸和微量氢组成。

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

以及强碱，如氢和氢钾。

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.

理论上你可以拥有更高pH值。水中极高浓度氢可以达到pH 15，这意味每1亿个氢根离子中只有一个氢离子。

And in that remember we're looking at the amount that we have to add of a certain solution, in this case is was sodium hydroxide.

记住, 我们正在考虑必须添加溶液量, 在这种情况下是氢。

This is done by soaking them in water or brine or brine followed by a solution of sodium hydroxide known as lie.

这是通过将它们浸泡在水中或盐水中，然后再用一种称为碱液氢溶液来完成。

Or some of the cephalopods like some of the really toxic octopi also have this tetrodotoxin inside it and shuts them down.

某些头足类动物，比如一些剧毒章鱼，体内也含有这种四毒素，从而使其瘫痪。

These chemicals are Sodium hydroxide, which is a base.

氢，它是一种碱 碱。

Supposedly, this alters the chemical composition of the baking soda to make it perform more like lye.

据说，这会改变小苏打学成分，使其更像氢效果。

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

所以那是大约294开尔文，现在我将加入100毫升氢。

Tetrodotoxin is found in lots of other animals.

四毒素存在于许多其他动物体内。

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.

记得我们可以在教科书后面或在线查找所有产物和反应物标准生成焓，盐酸和氢之间学反应会产生液态水和氯。

The real way to do this is to use a food grade lye, but we're doing a work around of baking soda that has been previously baked in the oven at 250 degrees Fahrenheit for an hour.

真正方法是使用食品级氢，但我们这里用是之前在烤箱中以250华氏度烘烤了一小时小苏打作为替代。

She then left the olives to soak and sample them from time to time until 273 days had passed This being the normal period for which olives are stored in brine prior to processing with lie.

她然后让橄榄浸泡，并不时品尝，直到273天过去。这是橄榄在用氢处理前，通常在盐水中储存正常时间。

If instead of adding 30.0 milliliters of 1.0 molar sodium hydroxide, let's say we had to add 25.0 milliliters of a 0.5 molar sodium hydroxide solution.

如果不是添加30.0毫升1.0摩尔氢, 假设我们必须添加25.0毫升0.5摩尔氢溶液。

Remember I told you it's 1.0 molar sodium hydroxide solution.

记得我告诉过你这是1.0摩尔氢溶液。

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.

盐酸标准生成焓是-167.2千焦每摩尔；氢是-469.15千焦每摩尔； 液态水是-285.8千焦每摩尔； 氯是-407.27千焦每摩尔。

But it's kind of an interesting story of how they took this one person, fed him some tetrodotoxin poison and supposedly kept him as a zombie for years.

但这背后其实有一个颇为有趣故事：他们找到一个人，给他喂食了四毒素， 据称将其变成了僵尸， 并维持了多年。

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

（咕哝）现在我要加入相同量氢溶液。

As we add the sodium hydroxide, the pH is going to start to climb gradually.

当我们添加氢时，pH 值会开始逐渐上升。
