- 1. Chemistry in EverydayLife • Understanding the Role of Chemistry Around Us • Your Name / Institution / Date
- 2. Introduction • • Chemistryis a part of everything we do • • Found in food, cleaning, medicine, emotions, and more
- 3. Chemistry in Food •• Preservatives (e.g., sodium benzoate) • • Food colors and flavor enhancers • • Acids and bases in taste (citric acid, baking soda)
- 4. Cooking as Chemistry •• Chemical reactions occur during cooking • • Maillard reaction – browning of food • • Use of acids, bases, and heat
- 5. Soap and Detergents •• Made using saponification reaction • • Surfactants reduce surface tension • • Help remove grease and dirt
- 6. Cosmetics and PersonalCare • • Shampoos, creams, perfumes – all are chemical formulations • • Contain alcohols, esters, emulsifiers
- 7. Medicines and Drugs •• Antibiotics, painkillers, antacids • • Chemical compounds to cure or relieve symptoms
- 8. Chemistry in Emotions •• Neurotransmitters like dopamine, serotonin • • Affect mood, motivation, and behavior
- 9. Polymers and Plastics •• Found in bottles, bags, containers • • Types: Polyethylene, PVC, Teflon
- 10. Textiles and Fabrics •• Cotton, polyester, nylon – made/treated with chemicals • • Dyes, waterproofing, and wrinkle resistance
- 11. Cleaning Agents • •Bleach (NaClO), vinegar (acetic acid) • • Disinfectants and sanitizers – alcohol-based
- 12. Chemistry in Environment •• Air and water quality monitored using chemistry • • Pollution control and waste management
- 13. Fuels and Energy •• Petrol, diesel – hydrocarbons • • Battery chemistry (Li-ion, alkaline cells)
- 14. Chemistry in Agriculture •• Fertilizers – NPK compounds • • Pesticides and insecticides • • Soil pH and crop yield
- 15. Construction and Materials •• Cement, glass, steel – made via chemical processes • • Paints and coatings for durability
- 16. Water Purification • •Chlorination, filtration • • Chemical coagulants (alum), activated carbon
- 17. Chemistry in Packaging •• Food-safe plastics, Tetra Pak, wax coatings • • Prevent spoilage and extend shelf-life
- 18. Colors and Dyes •• Synthetic and natural dyes • • Used in art, fabrics, and indicators
- 19. Chemistry in Electronics •• Semiconductors, printed circuit boards • • Use of silicon, rare earth elements
- 20. Conclusion • • Chemistryis vital for modern living • • Enhances comfort, health, and sustainability
