**Acids and bases** are two important types of substances that play a major role in chemistry and in the natural world. Acids are generally known for their sour properties, while bases often have a bitter taste and slippery feel.
The strength of an acid or base can be described using the **pH scale**, which ranges from 0 to 14. A pH below 7 is acidic, 7 is neutral, and above 7 is basic.
Acids and bases are found everywhere—from **lemon juice and vinegar to soap, soil, oceans, and our bodies**. They also interact through a process called **neutralization**, where an acid and a base react to form products such as salt and water.
Understanding acids and bases helps us appreciate the delicate **chemical balance of nature** and their importance in everyday life.
