Definitions [6]
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.
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.
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.
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.
An alkali is a basic hydroxide which when dissolved in water produces hydroxyl (OH-) ions as the only negatively charged ions.
Define neutralization.
Neutralization: A chemical reaction in which a base or an alkali reacts, with an acid to produce salt and water only.
\[\ce{\underset{\text{sodium hydroxide}}{NaOH(aq)} +\underset{\text{hydro chloride acid}}{HCl(aq)}->\underset{\text{sodium cholride}}{NaCl(aq)}+\underset{\text{water}}{H2O}}\]
