Role of Water in Showing Acidic and Alkaline Properties (2)

The classification of acids based on the basicity of the acids (3)

Triprotic acid

Monoprotic acid

Hydrochloric acid, HCl produces one H+ ion per acid molecule

Diprotic acid

Sulphuric acid, H2SO4 produces two H+ ions per acid molecule

Triprotic acid

Phosphoric acid, H3PO4 produces three H+ ions per acid molecule

Example of base (1)

Metal oxides

Example of base (2)

Sodium hydroxide

The reason which potassium hydroxide, KOH and sodium hydroxide, NaOH are alkalis

Because they are soluble in water

Definition of alkali

A base that is soluble in water

Example of alkali (1)

Potassium hydroxide, KOH

Example of alkali (2)

Sodium hydroxide, NaOH
