Local anesthetic agents with vasoconstrictors are indeed generally more acidic than their plain counterparts, primarily due to the addition of sodium bisulfite. Sodium bisulfite is added as a preservative to prolong the shelf life of the vasoconstrictor, such as epinephrine, which is prone to oxidation. This addition makes the solution more acidic, which is correctly related to the preservation of the vasoconstrictor component.
