Acids and bases are fundamental concepts in chemistry that play crucial roles in various chemical reactions and everyday life. Understanding these substances is essential for students and enthusiasts alike.
What are Acids and Bases?
Acids and bases are types of chemical compounds that exhibit distinct properties. Acids are known for their ability to donate protons (H+) in a chemical reaction, while bases accept protons. The strength of an acid or base is measured on the pH scale, ranging from 0 to 14. Substances with a pH below 7 are acidic, while those with a pH above 7 are basic. A pH of 7 is neutral.
Examples of Acids
- Hydrochloric acid (HCl)
- Sulfuric acid (H2SO4)
- Nitric acid (HNO3)
- Acetic acid (CH3COOH)
- Citric acid (C6H8O7)
- Phosphoric acid (H3PO4)
- Carbonic acid (H2CO3)
- Hydrofluoric acid (HF)
- Formic acid (HCOOH)
- Hydrobromic acid (HBr)
Examples of Strong Acids
- Perchloric acid (HClO4)
- Sulfuric acid (H2SO4)
- Nitric acid (HNO3)
