Acid & Bases

The magnitude of Ka indicates the tendency of an acid to ionize in water. Since [H+] is found in the numerator of the equilibrium constant expression for the dissociation of an acid, a stronger acid will have a larger Ka val

Weak acids

Citric acid (C8H6O7) is a weak acid

Acetic acid is a weak acid

K = (Ka*Kb)/Kw
