Acids and bases are two types of chemical compounds that have different properties and characteristics.
Acids:
- Acids are substances that have a pH level lower than 7.
- They are sour in taste and can be corrosive.
- Acids react with metals to produce hydrogen gas.
- Examples of acids include hydrochloric acid, sulfuric acid, and citric acid.
Bases:
- Bases are substances that have a pH level higher than 7.
- They are bitter in taste and feel slippery to the touch.
- Bases can neutralize acids to form salts and water.
- Examples of bases include sodium hydroxide, ammonia, and baking soda.
Acids and bases can react with each other in a chemical reaction called neutralization, where they cancel out each other's properties to form a salt and water. This reaction is often used in various applications, such as in the production of soaps and detergents.

Acids
- Definition: Substances that release hydrogen ions (H+) in water.
- Properties:
- Taste sour
- Turn litmus paper red
- React with bases to form salts
- Corrode metals
- Examples: Hydrochloric acid (HCl), sulfuric acid (H2SO4), nitric acid (HNO3)
- pH Range: Below 7 (0-6)
Bases
- Definition: Substances that release hydroxide ions (OH-) in water.
- Properties:
- Taste bitter
- Turn litmus paper blue
- React with acids to form salts
- Feel slippery
- Examples: Sodium hydroxide (NaOH), potassium hydroxide (KOH), ammonia (NH3)
- pH Range: Above 7 (8-14)
Neutralization Reaction:
- When an acid and a base react in stoichiometric proportions, they undergo a neutralization reaction.
- The products are salt and water.
- The resulting solution has a neutral pH of 7.
pH Scale:
- Measures the concentration of hydrogen ions in a solution.
- Ranges from 0 to 14.
- 0-6: Acidic
- 7: Neutral
- 8-14: Basic
Importance of Acids and Bases:
Acids and bases are essential for many biological and industrial processes. They are involved in:
- Biological processes: Digestion, respiration, blood regulation
- Industrial applications: Manufacturing of fertilizers, dyes, pharmaceuticals, plastics
- Everyday use: Batteries, cleaning products, household appliances
