Introduction

Acids and bases are important concepts in science and chemistry. Understanding the properties and behavior of acids and bases is crucial for a wide range of applications, from everyday household products to industrial processes.

What are Acids?

Acids are substances that have a sour taste and can turn blue litmus paper red. They are also known to release hydrogen ions (H+) when dissolved in water. Common examples of acids include citrus fruits (such as lemons and oranges) and vinegar.

Properties of Acids

Acids have a pH less than 7.
They react with metals to produce hydrogen gas.
Acids neutralize bases.

What are Bases?

Bases are substances that have a bitter taste and feel slippery to the touch. They are known to turn red litmus paper blue. Bases are also called alkalis. Common examples of bases include soaps and household cleaning products.

Properties of Bases

Bases have a pH greater than 7.
They feel slippery to the touch.
Bases neutralize acids.

pH Scale

The pH scale is a measure of the acidity or basicity of a solution. It ranges from 0 to 14, with 7 being neutral. Substances with a pH less than 7 are acidic, while substances with a pH greater than 7 are basic.

Common Examples of Acids and Bases

Acids	Bases
Lemon juice	Soap
Vinegar	Ammonia
Battery acid	Baking soda

Neutralization

Neutralization is a chemical reaction between an acid and a base, resulting in the formation of water and a salt. This process is commonly used to neutralize acidic or basic solutions.
