According to the Arrhenius definition of acids and bases, what product is always formed when an acid and base neutralize each other?
  1. OH-
  2. H2O
  3. HCOOH
  4. CO2
  5. There is no defined product for the neutralization of an acid and base.
Explanation
Answer: E - The Arrhenius definition defines an acid as a hydrogen ion donator, and a base as a hydrogen ion acceptor. Thus, we cannot say for certain that a product is always formed when and acid and a base neutralize each other. For example H+ could be neutralized by NH2-, resulting in the formation of NH3, and not water.
