The chapter "Exploring Substances: Acidic, Basic, and Neutral" introduces students to the fundamental properties of different substances based on their acidic, basic, or neutral nature. It explains how to identify these substances using various indicators like litmus, turmeric, China rose, and phenolphthalein. A key concept covered is neutralisation, the reaction between an acid and a base, and its applications in everyday life, such as treating indigestion, soil conditions, and factory waste.
