And so each of these have a different pKa value.

因此它各自都有不同的 pKa 值。

Well the first thing is the pKa, which is going to be the equilibrium constant.

首先是 pKa，它是平衡常数。

And also we can use our pKa values, which is remember looking at the concentration of reactants and products.

我还可以使用 pKa 值，记住查反应物和产物的浓度。

So our pH and our pKa values are essentially equal to each other.

所以我的 pH 值和 pKa 值基本上相等。

So if our pH value is less than our pKa that means we have more of this weak acid.

因此，如果我的 pH 值小于 pKa，则意味着我有更多的这种弱酸。

And so did you learn that when we're creating a good buffer solution we want to keep our pH and pKa values equal to each other?

那么您是否知道，当我配置良好的缓冲溶液时，我希望保持 pH 值和 pKa 值相等？

And did you learn that changes in the pH related to the pKa tells us if we're moving more towards the left, more of the acid or more of the base?

您是否知道， 与 pKa 相关的 pH 值的变化可以告诉我是向左移动更多，酸性更多还是碱更多？

Well if we keep our Ka value equal to our concentration of our hydronium ion or if we keep our pH equal to pKa value, that's going to create a good buffer.

好吧， 如果我保持 Ka 值等于我的水合氢离子的浓度， 或者如果我保持 pH 值等于 pKa 值，那就会产生一个良好的缓冲液。
