What you need to learn in this chapter
In this chapter, we will learn about the role of water in showing acidic and alkaline properties. We will define acids and alkalis and understand the meaning of basicity of an acid.
Next, we will explore pH value and its uses. We will learn how to calculate pH values of acids and alkalis.
Moving on, we will study the strength of acids and alkalis. We will define strong and weak acids and alkalis and explain their strength based on their degree of dissociation in water.
Finally, we will explore the chemical properties of acids and alkalis. We will carry out reactions to understand how acids react with bases, reactive metals, and metal carbonates. Similarly, we will study the reactions of alkalis with acids, metal ions, and ammonium salts.
