Neutralisation: A Reaction in which Acidity or Alkalinity is removed.
- When an alkali is added to an acid, the pH of the mixture rises as the alkali reacts with it forming a neutral solution.
- When an acid is added to an alkali, the pH of the mixture falls as the acid reacts with it forming a neutral solution.
A Neutralisation reaction involving an acid and base (alkali) will always produce a salt and water:
Acid + Base (Alkali) → Salt + Water
When the H+ Ions from an acid react with the OH– ions from an alkali, this forms water, causing the neutral solution to be formed:
H+ (aq) + OH– (aq) → H2O (l)
The name of the Salt produced can be predicted:
