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

以及强碱，如氧化钠和氧化钾。

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

（着）现在我要加入相同量的氧化钠溶液。

Tetrodotoxin is found in lots of other animals.

四氧化钠毒素存在于许多其他动物体内。

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

当我们添加氧化钠时，pH 值会开始逐渐上。

These chemicals are Sodium hydroxide, which is a base.

氧化钠，它一种碱 碱。

And now we're just pouring straight sodium hydroxide in there.

现在我们直接将氧化钠倒入其中。

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

据说，这会改变小苏打的化成分，使其更像氧化钠的效果。

It looks like when we're adding about 30 milliliters of sodium hydroxide, that's when we hit that point.

看起来当我们添加大约30氧化钠时, 就我们达到这一点的时候。

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

所以那大约294开尔文，现在我将加入100的氧化钠。

So I'm going to let that sodium hydroxide run out.

所以我要让氧化钠流出。

Well in the beginning as we add that sodium hydroxide, it's reacting with the oxalic acid.

一开始, 当我们添加氧化钠时, 它会与草酸发生反应。

In other words we have too much sodium hydroxide.

换句话说, 我们有太多的氧化钠。

So let's say I had to add 30.0 milliliters of that sodium hydroxide solution to hit that exact equivalence point.

所以, 假设我必须添加30.0的氧化钠溶液才能达到精确的等价点。

This is going to be sodium hydroxide which is a base.

这将氧化钠，一种碱。

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.

然后氧化钠，另一种我连最恨的敌人都不希望它有的物质， 尽管我很高兴我们有它。

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

这通过将它们浸泡在水中或盐水中，然后再用一种称为碱液的氧化钠溶液来完成的。

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，比如一些剧毒的章鱼，体内也含有这种四氧化钠毒素，从而使其瘫痪。

It's just because we're just pouring straight sodium hydroxide in.

这仅仅因为我们只直接将氧化钠倒入其中。

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

记得我告诉过你这1.0摩尔氧化钠溶液。

That's 1 mole of sodium hydroxide for every 1.0 liter of solution.

每1.0溶液中含有1摩尔的氧化钠。
