5. Lewis Lewis defines an acid as any species that accepts lone pairs electrons. Lewis defines an acid as any species that accepts lone pairs electrons. Lewis defines a base as any species that donates lone pair electrons. Lewis defines a base as any species that donates lone pair electrons.

6. Aqueous Solution When you apply pH and pOH to aqeous (water based) solutions, the water dissociates the pH and pOH allowing it to yield a hydrogen ion and a hydroxide ion.
