Understanding the Chemical Equilibrium Constants Comprehensively

Chemical equilibrium constant was the mark of achieving dynamic balance of reversible chemical reaction under certain conditions.The core concept of the equilibrium constant should be grasped from the definition,physical meaning,calculation and different phase to understand the chemical equilibrium constant.The chemical equilibrium theory,the ionization equilibrium theory and salt hydrolysis equilibrium theory were mastered to understand the equilibrium movement law essentially,and laid the foundation for dissolution equilibrium of teaching.
