Neutralisation
Neutralisation is the reaction in which an acid and a base react to form salt and water, usually with release of heat.
Practice This ConceptMain explanation
Teacher explanation
Neutralisation is one of the most useful ideas in this chapter because it appears in stomach medicine, soil treatment, and sting relief. When an acid is too strong, a base can reduce its effect. When a base is too strong, an acid can reduce that effect. The final result is a safer, less extreme solution.
Example
An antacid tablet helps reduce excess acid in the stomach by neutralising it.
Simple analogy
Neutralisation means balance: acid and base cancel excess action.
Common confusion
Students sometimes write only salt is formed and forget water. They also forget that the reaction reduces excess acidity or basicity.
Exam tip
In exam answers, always mention the role of acid, base, and the useful result, especially in daily-life examples.
