The same can be said for strong bases and their weak conjugate acids.

弱共轭酸也是如此。

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

以，如氢氧化钠和氢氧化钾。

Take sodium hydride, for example — a superbase that’s just sodium bonded to a hydrogen.

以氢化钠例——这是一种，由钠与氢结合而成。

We could have a strong acid and a strong base.

我们可以得到酸和。

We could have a weak acid and a strong base.

我们可以得到弱酸和。

Just like with super-strong acids, there’s a whole class of bases that are especially strong, called superbases.

就像酸一样，也有一类特别的，称。

It's got an aluminum hydroxide, which is a strong base, so it's neutralizing the stomach acid production.

它含有氢氧化铝， 这是一种，因此能中和胃酸分泌。

So what would it look like if we're doing a strong acid and a strong base?

那么如果我们使用酸和，结果会是什么样子呢？

When we're adding a strong base to a strong acid.

当我们将添加到酸中时。

Now what happens if we add a strong base to a weak acid?

现在，如果我们将添加到弱酸中会发生什么？

If we were to actually graph the pH over time it would look like something like this, when we add a strong base to a strong acid.

如果我们实际上要绘制 pH 值随时间变化的图表，当我们将添加到酸中时，它看起来会像这样。

And so what happens is we can add strong acids and we can add strong bases and it's going to keep that pH around a stable set point.

所以我们可以添加酸和，这样就可以将 pH 值保持在一个稳定的设定点左右。

And so in this case we're going to have acetic acid in the bottom and then we're going to add a strong base, so that's sodium hydroxide.

在这种情况下， 我们将在底部加入乙酸， 然后添加，也就是氢氧化钠。
