1) The salts formed by the partial replacement of the hydroxyl group of a di- or tri- acidic base by an acidic radical.
Mg (OH) 2 + HCl Mg (OH) Cl + H2O
2) They are complex substances that acquire separate colours in acidic and basic media.
Litmus, methyl orange, phenolphthalein etc.
Examples of acid-base indicators are as follows:
Methyl orange, phenolphthalein, turmeric juice, red-cabbage juice etc.
4) The number of replaceable hydronium ions (H3O+) in an acid is called basicity of an acid.
The number of hydronium ions (H3O+) that can be produced by the ionisation of one molecule of that acid in aqueous solution.
5) The number of replaceable hydroxyl (OH-) Ions in a base is called the acidity of that base.
The number of hydroxyl ions (OH-) that can be produced by the ionisation of one molecule of that base in aqueous solution.
