And you learned about the equilibrium constant for that reaction, which has a special name: the water dissociation constant.

你不太可能碰到它们——至少我这样希望，像盐酸或硝酸，电离程度很强。

You've learned how to calculate an equilibrium constant, Keq.

您已经学习了如何计算平衡常数 Keq。

There's actually a way to determine the equilibrium constant from a measured voltage, and vice versa.

实际上有一种方法可以根据测得的电压确定平衡常数， 反之亦然。

Therefore, the equilibrium constant is only true for a specific temperature.

因此， 平衡常数仅适用于特定温度。

The symbol for this kind of equilibrium constant is Ka, for an acid, or Kb for a base.

这种平衡常数的符号是​​ Ka（酸）或 Kb（碱）。

Fortunately for us, chemists have already figured out the equilibrium constants for most common reactions.

对我们来说幸运的是， 化学家已经计算出大多数常见反应的平衡常数。

Now I gotta point out here that the electrical potential of a redox reaction is related to its equilibrium constant.

现在我要在这里指出， 氧化还原反应的电势与其平衡常数有关。

The first and most important thing you need to do equilibrium calculations is the equilibrium constant.

您需要进行平衡计算的第一件也是最重要的事情是平衡常数。

Now we apply these figures to our formula for the equilibrium constant.

现在我们将这些数字应用到平衡常数的公式中。

Chemists often know not only the equilibrium constant for a reaction, but also how much of each reactant is available.

化学家通常不仅知道反应的平衡常数，而且知道每种反应物的可用量。
