Acids, Bases and Salts

Core concepts of acids, bases and salts organised into fewer broad chapters with multiple topics.

Learn what acids are, their properties, common examples, everyday uses, and how acids react with metals, bases, and indicators.

Understand what bases are, their properties, examples, everyday uses, and how bases react with acids, indicators, and metals.

Learn what salts are, how they are formed, their properties, types, everyday examples, and the reactions involved in salt formation.

4.Physical Properties of Acids

Learn the physical properties of acids in simple terms, including taste, smell, colour, solubility, conductivity, and effect on indicators.

5.Physical Properties of Bases

Learn the physical properties of bases in simple language, including taste, texture, colour, solubility, conductivity, and effect on indicators.

6.Strength of Acids and Bases

Understand the strength of acids and bases, what makes them strong or weak, their ionisation, pH values, and simple examples explained clearly.

7.Concentration and Dilution of Acids and Bases

Learn what concentration and dilution mean in acids and bases, with simple explanations, examples, and clear differences between concentrated, dilute, strong, and weak acids.

8.Definition of pH

Learn the simple definition of pH, what pH stands for, how pH indicates acidity or basicity, and why the pH scale is important in everyday life.

Learn how to measure pH using litmus paper, pH paper, universal indicator, and digital pH meters with simple explanations.

10.Common Salts & Their Uses

Learn the properties and everyday uses of common salts like NaCl, CaCl₂, KNO₃, baking soda, washing soda, and gypsum.
