The four acids will require the same volume of the base to reach the equivalence point.
Strong acids completely ionize in waters while weak acids are only partially ionized in waters.
At 0.5 M concentration, the hydrogen ion concentrations of all four acids would be the same.
This means that each of the acids will require an equal volume of base concentration in order to get neutralized.
