The method for calculating the equilibrium constant, pH and degree dissociation of weak acids and bases should be explained. Concept Introduction: A system is referred to be in a state of equilibrium if the rate of forward reaction equals the rate of the reverse reaction. A system at equilibrium is characterized by the equilibrium constant which depends on the concentrations of the reactants and products. In the case of dissociation of weak acids and bases, there is a dynamic equilibrium between the acid (or base) and its constituent ions The equilibrium constant is such cases is referred to as the acid dissociation constant K a or the base dissociation constant K b

The method for calculating the equilibrium constant, pH and degree dissociation of weak acids and bases should be explained.

Concept Introduction:

A system is referred to be in a state of equilibrium if the rate of forward reaction equals the rate of the reverse reaction.

A system at equilibrium is characterized by the equilibrium constant which depends on the concentrations of the reactants and products.

In the case of dissociation of weak acids and bases, there is a dynamic equilibrium between the acid (or base) and its constituent ions

The equilibrium constant is such cases is referred to as the acid dissociation constant K_a or the base dissociation constant K_b

Next, record any regiochemistry or stereochemistry considerations relevant to the reaction. You should also record any key aspects of the mechanism, such as forma- tion of an important intermediate, as a helpful reminder. You may want to keep track of all reactions that make carbon-carbon bonds, because these help you build large molecules from smaller fragments. This especially applies to the reactions in…
