a model describing acids as electron pair acceptors and bases as electron pair donors
a model in which acids increase the concentration of hydroxide ions in solution
a model that defines acids as substances that change color in the presence of bases
conjugate acid
the species produced when a base accepts a hydrogen ion from an acid
the species produced when an acid donates a hydrogen ion to a base
a substance that increases the concentration of hydroxide ions in solution
a molecule that cannot accept or donate hydrogen ions
conjugate base
the species that results when an acid donates a hydrogen ion to a base
the species that results when a base donates a hydrogen ion to an acid
the product formed when a salt dissolves in water
the original acid before any reaction occurs
conjugate acid-base pair
two substances related to each other by the donating and accepting of a single hydrogen ion
two substances that have identical chemical properties
two substances that differ by a single electron
two substances that are unrelated in chemical reactions
amphoteric
