在普通化学的学习和教学中,经常遇到一些平衡问题。诸如电解质电离平衡、化学平衡、溶解平衡、络合平衡、氧化还原平衡等。从某种意义上讲,任何化学反应都有一定程度的可逆性,在一定条件下都能达到某种平衡状态。 对于某平衡体系,其平衡常数是该平衡状态的一个重要性质,也是我们讨论平衡问题一个必不可少的重要数据。这个常数一般可以从实验测得或通过热力学计算获得。现就平衡常数的应用谈点认识。
In ordinary chemistry learning and teaching, we often encounter some problems of balance. Such as electrolyte ionization equilibrium, chemical equilibrium, dissolution equilibrium, complex equilibrium, redox balance and so on. In a sense, any chemical reaction has a certain degree of reversibility, under certain conditions can reach a certain balance. For a certain equilibrium system, its equilibrium constant is an important property of the equilibrium state, and it is also an indispensable important data for us to discuss the balance problem. This constant can generally be obtained experimentally or through thermodynamic calculations. Now on the application of equilibrium constant talk about understanding.
