The acidity ( p K a ) values and chemical equilibrium position should be draw and identified for the given molecules by using its structures. Concept Introduction : Chemical equilibrium: The term applied to reversible chemical reactions. It is the point at which the rate of the forward reaction is equal to the rate of the reverse reaction. The equilibrium is achieved; the concentrations of reactant and products become constant. Acid-Base Reaction: The equal ratio of acid and base are place together, two molecules react to neutralize the acid base properties and producing salt. The hydrogen ions are cation of the combines with the hydroxyl anions of the base to from water. The compound formed by the cation of the anion of the acid is called a salt. Strength p K a : This is measure for different acid strength. It depends on the identity and chemical properties of the various mineral acids and measure of hydrogen ions. For example more acidic compounds is easily a proton is lost, thus the lower pH values. To identify: The given set of molecules acidic strength should be identified.

Concept Introduction:

Chemical equilibrium: The term applied to reversible chemical reactions. It is the point at which the rate of the forward reaction is equal to the rate of the reverse reaction. The equilibrium is achieved; the concentrations of reactant and products become constant.

Acid-Base Reaction: The equal ratio of acid and base are place together, two molecules react to neutralize the acid base properties and producing salt. The hydrogen ions are cation of the combines with the hydroxyl anions of the base to from water. The compound formed by the cation of the anion of the acid is called a salt.

Strength pKa : This is measure for different acid strength. It depends on the identity and chemical properties of the various mineral acids and measure of hydrogen ions. For example more acidic compounds is easily a proton is lost, thus the lower pH values.

To identify: The given set of molecules acidic strength should be identified.
