When acid meets base, something remarkable happens: they cancel each other out completely, producing only salt and water. This is neutralisation one of the most useful reactions in all of applied chemistry. It is what makes antacid tablets work, what farmers use to rescue acidic soil, what factories use to make fertilisers, and what your body uses every day in digestion. Today you master Neutralisation: the reaction, the ionic explanation, and the six key applications that make it one of chemistry most practically important concepts.
