Neutralisation Reaction
Understanding what happens when an acid reacts with a base.
Core concept
Farmers use neutralisation when they add lime (a base) to acidic soil to make it more suitable for growing crops. In factories, neutralisation is used to safely treat acidic or basic waste before it is released into the environment, preventing damage to rivers and ecosystems. The general pattern of this reaction is: Acid + Base → Salt + Water, and the type of salt formed depends on which specific acid and base were used.
