Acids and Bases: A Comprehensive Guide
Acids and bases are like the yin and yang of chemistry. They’re two sides of the same coin, and we couldn’t do without either of them. But what exactly are they, and how do they work?
Let’s dive in and break it down.
Properties of Acids and Bases
Acids are sour, corrosive, and can react with metals. They have a pH below 7 and are made up of hydrogen ions (H+). Bases, on the other hand, are bitter, slippery, and can neutralize acids. They have a pH above 7 and are made up of hydroxide ions (OH-).
When an acid and a base react, they neutralize each other, forming salt and water. This process is called a neutralization reaction.
Important Note: Acids and bases are also known as ionic compounds because they contain ions (charged particles).
Measuring Acidity and Basicity
The pH scale is a measure of how acidic or basic a substance is. It ranges from 0 to 14, with 7 being neutral. Acids have a pH below 7, and bases have a pH above 7.
A simple way to test the acidity or basicity of a substance is to use litmus paper.
Litmus paper is a special type of paper that changes color depending on the pH of the solution it’s placed in. In acidic solutions, it turns red; in basic solutions, it turns blue.
Here are some examples to help you understand:
- Coffee is slightly acidic, with a pH of around 5.
- The pH scale ranges from 0 (extremely acidic) to 14 (extremely basic).
- Litmus paper is red in acidic solutions and blue in basic solutions.
