WHAT ARE ACIDS?
Acids produce hydrogen ions in water.
Example of an acid (HA) in solution

WHAT ARE BASES?
They are metal oxides or metal hydroxides.
Examples:
Sodium hydroxide (NaOH)
Copper (II) oxide (CuO)
Copper (II) Oxide
NaOH
Can you name some other examples of
bases?

SOLUBLE BASES
Soluble bases are called alkalis
Alkali dissolves in water to produce hydroxide (OH-) ions

ACID AND BASE REACTION
The reaction between an acid and a base is called neutralisation.
Example 1:
Sodium hydroxide + hydrochloric acid Sodium chloride + water
Now, let’s write the chemical equation!NaOH + HCl NaCl + H2O

ACID AND BASE REACTION
Example 2
Copper (II) oxide + sulfuric acid copper(II) sulfate + water
Now, let’s write the chemical equation!CuO + H2SO4 CuSO4 + H2O

SUMMARY: NEUTRALISATION
REACTION Acid + Base Salt + water
Ionic Equation:
H+ (aq) + OH- (aq) H2O (l)
