1. Sulfuric Acid (H₂SO₄)
Industry: Fertilizers, chemicals, petroleum refining.
Use: Producing phosphoric acid (for fertilizers), detergents, batteries.
🔥 Fun Fact: It’s often called the “king of chemicals” because it’s used in the production of so many products.
2. Ammonia (NH₃)
Industry: Agriculture, refrigeration, textiles.
Use: Fertilizer (urea), cleaning solutions, synthetic fibers.
💨 Note: It’s a colorless gas with a sharp smell.
3. Chlorine (Cl₂)
Industry: Water treatment, plastics, pharmaceuticals.
Use: Disinfecting drinking water, making PVC plastic.
⚡ Warning: Toxic in large amounts!
4. Sodium Hydroxide (NaOH)
Industry: Paper, soap, textile, chemical manufacturing.
Use: Making soaps, detergents, drain cleaners.
🧼 Nickname: Also called “caustic soda.”
5. Nitrogen (N₂)
Industry: Electronics, food packaging, chemicals.
Use: Creating inert atmospheres, preserving food.
❄️ Trivia: Liquid nitrogen is used for cryogenic freezing!
6. Methanol (CH₃OH)
Industry: Chemicals, fuels, plastics.
Use: Production of formaldehyde, antifreeze, and biofuels.
🚗 Energy Note: A potential green fuel of the future.
7. Ethanol (C₂H₆O)
Industry: Pharmaceuticals, beverages, fuel.
Use: Alcoholic drinks, hand sanitizers, fuel additives.
🧴 Tip: Commonly seen in sanitizers today!
8. Hydrochloric Acid (HCl)
Industry: Steel, food, chemical manufacturing.
