30 Examples Of Chemistry In Everyday Life

Chemistry is the science that studies matter in terms of its composition, structure and properties . It also studies the changes that matter experiences, which can occur due to chemical reactions associated with the absorption or release of energy.

Chemistry opens up in different specialties:

  • Inorganic chemistry . It refers to all elements and compounds that are structurally based on carbon-hydrogen (CH) bonds. This does not mean that inorganic compounds cannot contain carbon or hydrogen. For example, carbon dioxide (CO 2 ) and hydrochloric acid (HCl) are inorganic compounds.
  • Organic chemistry . It studies compounds whose structure is based on covalent carbon-carbon (CC) and carbon-hydrogen (CH) bonds, although they may also contain other atoms such as nitrogen (N), oxygen (O), phosphorus (P) or sulfur (S).
  • Biochemistry . Studies the compounds and chemical reactions that develop in living organisms. It is based on organic chemistry.
  • Physicochemistry . He studies matter from a physical and chemical point of view.
    Analytic chemistry . Establishes methods and techniques to qualitatively (identify the substances in a sample) and quantitatively (determine the amount of a substance in a sample) analyze matter.

Although it is a complex discipline that requires a long preparation for its understanding and the advancement of knowledge , there are many applications of chemistry in everyday life since its application has improved our quality of life thanks to its combination with technology and industry. . For example: drinking water includes various chemical substances such as mineral salts.

Furthermore, chemical reactions occur in nature itself, in our own body and in everything around us.

Examples of chemistry in everyday life

  1. Pesticides are chemicals that are used to fumigate crops from which our food is obtained .
  2. Food provides us with energy through chemical reactions within cells .
  3. Each type of food has a different chemical composition, and offers different contributions to the body.
  4. Helium is used to inflate balloons.
  5. Photosynthesis is the chemical process by which plants synthesize (produce) saccharides.
  6. Various chemical substances such as mineral salts are included in drinking water .
  7. Chemical substances suspended in the air (known as smog) harm our health.
  8. Different colorants are chemical compounds used to give a more attractive appearance to certain industrial foods.
  9. Foods also enhance or change their flavor through chemical compounds called flavorings. Flavorings can imitate the flavor of a natural product or develop an unknown flavor.
  10. Sulfur is used in tire repair.
  11. Chlorine is used to whiten clothes, disinfect surfaces and in small proportions also to make water drinkable.
  12. Detergents are chemical products that are used to wash objects in our homes.
  13. Dyes are chemically developed to give color to the fabrics that make up clothing and other items of daily use.
  14. The natural fermentation of food (which makes it no longer usable) is a chemical process.
  15. To prevent food fermentation, chemicals known as preservatives are used.
  16. Means of transportation use different substances derived from petroleum that undergo chemical changes within their engines.
  17. Chemical analysis of tobacco smoke identified that it contains ammonia, carbon dioxide, carbon monoxide , propane, methane, acetone, hydrogen cyanide and other carcinogenic agents. This discovery alerted us to the need to protect passive smokers.
  18. We usually use multiple plastic materials. Plastic is a chemical product obtained through the polymerization (multiplication) of carbon atoms, which generates long chains. Most plastics are compounds derived from petroleum.
  19. Natural leather is also chemically treated with compounds that prevent its decomposition and can give it a different color than natural.
  20. Different chemical substances allow the potability of water to be identified, through the identification of bacteria and inorganic substances.
  21. The so-called “ecoleather” or synthetic leather is a polyurethane product, a chemical product that is obtained by the condensation of hydroxyl bases ( alkaline molecules ) and diisocyanates (highly reactive chemical compounds).
  22. Neon is used to obtain fluorescent lights.
  23. Breathing is an exchange of substances in the lungs, studied by biochemistry.
  24. Diseases are treated with chemical substances (active ingredient in medications) that allow the microorganisms that cause them to be eliminated.
  25. The different mineral salts are used by the body to sustain all its vital processes.
  26. Knowledge of smog and its components allows us to develop chemical substances (cosmetics) that counteract its negative effects on our skin.
  27. Forensic chemistry studies organic and inorganic compounds found at crime scenes, collaborating with police investigations.
  28. Even the most basic foods like kitchen salt (NaCl) are chemical compounds: salt is made up of cations (positively charged ions, Na + ) and anions (negatively charged ions, Cl  ) linked through ionic bonds .
  29. Each part of our body has a specific composition that it needs to maintain to remain healthy. For example, nails are a compound of amino acids and different inorganic substances such as calcium and sulfur.
  30. The chemical composition of blood includes sugars, amino acids, sodium, potassium, chlorides and bicarbonates.
