Solutions are ACIDIC if they have more “acid molecules” then base moleculesSolutions are BASIC if they have more “base molecules” then acid molecules
OVERALL DEFINITIONS
Solutions are NEUTRAL if they have equal quantities of both

Bronsted-Lowry Definition
-Donate H+ ions to other compounds -ACIDS ARE PROTON DONORS-A proton and H+ are the same thing
ACIDS
