Definitions [7]
Define Acid.
An acid is a compound which when dissolved in water produces hydronium ion(H3O+), the only positively charged
ion and a negative ion.
Define a base.
A base is defined as a chemical compound that, when it reacts with a hydronium ion or H+ ions furnished by an acid, forms a salt and water only.
Define the term ‘basicity’ of an acid.
The basicity of an acid is defined as the number of hydronium ions (H3O+) that can be produced by the ionization of one molecule of that acid in aqueous solution.
Acids are defined as compounds which contain one or more hydrogen atoms and when dissolved in water, produce hydronium ions (H3O+) the only positively charged ions.
An alkali is a basic hydroxide which when dissolved in water produces hydroxyl (OH-) ions as the only negatively charged ions.
A base is either a metallic oxide or a metallic hydroxide or ammonium hydroxide which reacts with hydronium ions of an acid to form a salt and water only.
Define neutralization.
Neutralization: A chemical reaction in which a base or an alkali reacts, with an acid to produce salt and water only.
