Acid vs BaseAcidic Solutions-contain more hydrogen ions (H+) than hydroxide ions (OH-)
Basic solutions contain more hydroxide ions than hydrogen ions

Water=NeutralThere are equal amounts of hydrogen ions as hydroxide ions
Note: H3O+ is the same as H+

Brønsted-Lowry AcidAn acid is something that donates a hydrogen
An acid is something that accepts a hydrogen

Brønsted-Lowry Conjugate Acids and Bases
Conjugate Acid: the species produced when a base accepts a hydrogen
Conjugate Base: the species produced when an acid donates a base

Polyprotic AcidsWhen an acid donates more than one hydrogen-one is lost at a time!
