Chem 12 Acid Base Definitions

Acid (BL)

A proton donor

Base (BL)

A proton acceptor

Strong Acid

A proton donor that dissociated completely in water (doesn’t go into equilibrium)

Weak acid

A proton donor that dissociates partially in water, goes into eqm

Strong Base

A proton acceptor that dissociates completely in water, doesn’t go into eqm

Weak base

A proton acceptor that dissociates partially in water, goes into equilibrium

Amphiprotic

Can donate or accept a proton

Amphoteric

Can be an acid or a base

Indicator

A weak proton donor whose protonated colour differs from its deprotonated colour

Neutralization

A reaction in which the properties of an acid and properties of a base are destroyed.

Titration

The volumetric addition of a standardized reagent to another

Buffer

The combination of a weak acid and its conjugate base. An eqm that shifts.

Ideal buffer

A weak acid and its conjugate base in equimolar quantities (50% WA 50%CB)
