We add an acid to water, which creates equilibrium. Subsequently, we add more conjugate base ions, usually in the form of sodium or potassium ions. Thus, there is a large amount of reactants on the both sides. Whenever we add acids or base, it reacts with hydrogen ions or creates more hydrogen ions. Whenever there is an increase or decrease in the H+ ions, the reaction equilibrium will shift to reduce the stress (Le Chatelier's Principle). Thus, buffer solution maintains the pH relatively constant. Buffer is a solution, which contains relatively high amount of a weak acid or base and its

conjugate pair. Buffers maintain pH at a relatively constant value despite small additions of acids or bases.

Considering an illustration for acids, even though the same works for bases: We add an acid to water, which creates equilibrium. Subsequently, we add more conjugate base ions, usually in the form of sodium or potassium ions. Thus, there is a large amount of reactants on the both sides. Whenever we add acids or base, it reacts with hydrogen ions or creates more hydrogen ions. Whenever there is an increase or decrease in the H+ ions, the reaction equilibrium will shift to reduce the stress (Le Chatelier's Principle).
