Abstract:

The two distribution fraction curves of a weak acid and its conjugated base are integrated to the pH-δA, δHA coordinate system. The two curves coincide with each other to form a conjugate distribution fraction curve, which is also an acid-base equilibrium curve. The titration process is discussed with images to understand how a specific equilibrium curve to a titration.

Key words: Titration curve equation, Conjugate curve, Titration fraction
