Class 7ScienceAcids, Bases and Salts

Neutralisation

Acid + Base → Salt + Water. This is neutralisation reaction. The acid and base neutralise each other. Examples: HCl + NaOH → NaCl + H₂O. Stomach acidity (excess HCl) treated with antacid (base like Mg(OH)₂). Ant bite (formic acid) → apply baking soda. Bee sting (alkali) → apply vinegar. Soil acidity → add lime.
