Ammonia isn’t just for household cleaning; it’s also used in fertilizers, refrigerants, and other industrial applications. In agriculture, ammonia plays a vital role in enhancing soil quality, making it an essential chemical for growing crops.

8. Hydrogen Peroxide (H₂O₂): A Household Disinfectant

Medical Uses of Hydrogen Peroxide

Hydrogen peroxide is commonly used as a disinfectant for minor cuts and scrapes. It works by releasing oxygen, which kills bacteria and cleans the wound. It’s a staple in first aid kits, providing an easy way to prevent infections from developing.

Cleaning and Whitening with Hydrogen Peroxide

In addition to its medical uses, hydrogen peroxide is a powerful household cleaner. It can be used to disinfect surfaces, whiten clothes, and remove stains. Its ability to kill germs makes it a reliable chemical for maintaining cleanliness in the home.

9. Aspirin (C₉H₈O₄): A Common Pain Reliever

Health Benefits of Aspirin

Aspirin is one of the most commonly used over-the-counter pain relievers. It’s effective in treating headaches, muscle aches, and fevers. In addition to its pain-relieving properties, aspirin also has anti-inflammatory effects, making it useful for managing conditions like arthritis.
