Define acid and base
Acid:
- An acid is a chemical substance that has a sour taste and can react with other substances to form salts.
- Acids can be found in everyday things like lemon juice, vinegar, and stomach acid.
- Acids can be strong or weak, depending on their ability to donate hydrogen ions (H+) when dissolved in water.
- Strong acids have a low pH value (less than 3.5), are highly reactive, and can be dangerous if not handled properly.
- Acids are commonly used in industries to make fertilizers, dyes, and plastics.
Base:
- A base is a chemical substance that has a bitter taste and can react with acids to form salts.
- Bases can be found in everyday things like baking soda, antacids, and cleaning products.
- Bases can be strong or weak, depending on their ability to accept hydrogen ions (H+) when dissolved in water.
- Strong bases have a high pH value (greater than 10.5), are highly reactive, and can be dangerous if not handled properly.
- Bases are commonly used in the production of soaps, detergents, and other cleaning products.
