Overview

Acids, bases and salts are three fundamental categories of chemical compounds that play crucial roles in everyday life and numerous industrial processes. This chapter explores the chemical properties of acids and bases, their reactions with various substances, the concept of pH scale, and the format

Key Concepts

Acids are chemical compounds that produce

Acids are chemical compounds that produce hydrogen ions (H⁺) or hydronium ions (H₃O⁺) when dissolved in water. Common acids include hydrochloric acid

Bases are chemical compounds that produce

Bases are chemical compounds that produce hydroxide ions (OH⁻) when dissolved in water. Examples include sodium hydroxide (NaOH), calcium hydroxide [C

Indicators are substances that change colour

Indicators are substances that change colour in the presence of acids or bases. Natural indicators include litmus (a purple dye from lichen that turns

The pH scale is a numerical

The pH scale is a numerical scale ranging from 0 to 14 that measures the concentration of hydrogen ions (H⁺ or H₃O⁺) in a solution. pH = 7 indicates a

A neutralisation reaction occurs when

A neutralisation reaction occurs when an acid reacts with a base to produce a salt and water. The general equation is: Acid + Base → Salt + Water. At
