Common reactions
In this four week course we will look at
reactions for:
Ionic compounds dissociating when in water
Ionic compounds precipitating when mixed
Acid + metals
Acid + metal hydroxides
Acids and Bases
Name and formula of common acids:
CH3COOH – Ethanoic acid
H3PO4 – Phosphoric acid
H2SO4 – Sulfuric acid
HNO3 – Nitric acid
H2CO3 – Carbonic acid
HCl – Hydrochloric acid
found on page 35
Bases are those compounds with
hydroxide in them.
Ie: Metal hydroxides
Acids and Bases
Acid and Metal
Reaction of an acid and metal produces
hydrogen gas and a salt
The hydrogen gas is made up of the
hydrogen ions ( ) from the acid.
The salt is made up of the metal ion
(positive) and the negative ion of the
acid
Acid and Metal
The general reaction is:
Acid + metal salt + hydrogen gas

Acid and Metal Hydroxide
(base) Reaction of an acid and metal hydroxide
produces water and a salt
The water is made up of the hydrogen ions
( ) from the acid and hydroxide ( )
ions from the base
The salt is made up of the metal ion
(positive) and the negative ion of the
acid
Acid and Metal Hydroxide
The general reaction is:
Acid + metal hydroxide salt + water
