1

Acid according to Arrhenius

A substance that produces H+ ions in water

2

Base according to Arrhenius

A substance that produces OH- ions in water

3

Strong acid

Ionise completely in water to produce a high concentration of H3O+ ions

Eg. HCL, H2SO4 or HNO3

4

Weak acid

Ionise incompletely in water to form a low concentration of H30+ ions

Eg. ethanoic acid, oxalic acid

5

Strong base

Dissociate completely in water

eg. NaOH, KOH

6

Weak base

Dissociates/ionises incompletely in water to form a low concentration of OH- ions

eg. ammonia, calcium carbonate, potassium carbonate, sodium hydrogen carbonate

7

Acid according to Lowry-Bronsted

Proton (H+) donor

8

Base according to Lowry-Bronsted

Proton (H+) acceptor

9

Concentrated Acid/Base

Large amount (number of moles) of Acid or base in proportion to volume of water

10

Dilute Acid or base

Small amount (number of moles) of Acid/base in proportion to volume of water

11

Amphiprotic

Substance that can act as an acid or base
