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

（咕哝着）现在我要加入相同氧化钠溶液。

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

我们添加氧化钠时，pH 值会开始逐渐上升。

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。

Sodium hydroxide and Hypochlorous acid from bleach neutralize these proteins.

漂白剂中亚氯酸会中和这些。

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

看起来我们添加大约30毫升氧化钠时, 就是我们达到这一点时候。

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毫升氧化钠。

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

所以我要让氧化钠流出。

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

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

一开始, 我们添加氧化钠时, 它会与草酸发生反应。

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毫升氧化钠溶液才能达到精确等价点。

In other words we have too much sodium hydroxide.

换句话说, 我们有太多氧化钠。

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

这将是氧化钠，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.

然后是氧化钠，另一种我连最恨敌人都不希望它有物质， 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氧化钠溶液来完成。

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

这仅仅是因为我们只是直接将氧化钠倒入其中。

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

记得我告诉过你这是1.0摩尔氧化钠溶液。

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％次氯酸钠和微氧化钠组成。

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

每1.0升溶液中含有1摩尔氧化钠。

So now I've already got to moles of sodium hydroxide.

所以现在我已经得到了氧化钠摩尔。

Let's say we start with a 1.00 molar sodium hydroxide solution.

假设我们从 1.00 摩尔氧化钠溶液开始。
