acids and bases

Acids

Proton donor/hydrogen ion donor

Base

Proton acceptor/hydrogen ion acceptor

Amphoteric

Can act as an acid and as a base (water)

H+ (hydronium ion) in water

H3O+

Strength of acid

The readiness of an acid to dissociate

Strength of base

The readiness of a base to associate

Strong bases

Readily accepts H+ or readily dissociates to form OH-

Strong acids

Dissociates into H+ (release all their protons (H+) into solution, leaving no undissociated acid molecules)

Weak acids

Dissociates partially in water - only a small fraction donate H+, the rest remain undissociated

Conjugate acid

The species formed when a base gains/accepts a proton (H+)

Conjugate base

The species formed when an acid loses/donates a proton (H+)
