Common Chemical Reactions in Everyday Life

There are many different numbers of chemical reactions in our day to day life that we notice. We often tend to see a flaky brown coloured layer that appears on the surface of several iron items, for example, the bodies of vehicles, gates, etc. During the festivities and celebrations of Diwali, we burn crackers which when burned, gives a bright light and sound. The bright light is a result of the burning of the components like magnesium that is used amongst one of the ingredients of the crackers and sparklers that we burn. In this article, we will study about these chemical processes in everyday life that we see around us.

Types of Chemical Reaction in Daily Life

1. Photosynthesis: 

The process of photosynthesis refers to the process by which the autotrophs tend to manufacture their food. It is one of the natural chemical reactions in everyday life. In the presence of chlorophyll and sunlight, the plants produce glucose in the form of energy from water and carbon dioxide from the environment.

6CO₂ + 6H₂O → C₆H₁₂O₆(aq) + 6O₂ (g)

2. Rusting: 

The process of the oxidation, which refers to the reaction in the presence of oxygen, gives a brown flaky layer that we often notice over the metal surfaces like the one on the iron. This layer is formed because of the oxidation of the topmost layer for forming the metal oxide. We know this and call it rust. Similarly, several layers get formed on other metals as well, for example, in silver in which a green coloured layer gets formed when it undergoes an oxidation reaction.

3. Cellular Respiration:

The process of respiration in humans in their lungs also involves a chemical reaction. In this reaction, the glucose molecules tend to undergo an oxidation reaction and produces water and carbon dioxide along with energy. This process happens at a cellular level and hence, is called cellular respiration.

C₆H₁₂O₆ (aq) + 6O₂ (g) → 6CO₂ (g) + 6H₂O(l) + energy

4. Anaerobic Respiration: 

When a living organism tend to undergo the process of fermentation, the components present in it which contain starch or sugar get converted to alcohol, acids and gases.

C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂

5. Combustion: 

The process of combustion is amongst the chemical changes in everyday life. It tends to involve the oxidation reaction of a material when it is exposed in the presence of both heat and oxygen from the surroundings to produce smoke, ash, and several other gases.

C + O₂ → CO₂

6. Acid-base Reactions: 

The acid-base reactions are also a part of the chemical reactions in our daily life. In these reactions, the weaker acids that are produced inside our mouth overnight because of the sugary foods and bacteria get neutralized in the presence of base that is present in the toothpaste that we use in the morning every day.

Acid + base → salt + water

In a similar manner, the oxide layer that is found on the metallic artefacts gets removed with the help of the weaker acids like vinegar. This process helps to give us the layer of the metal clean and a fresh new layer of the metal gets exposed.


FAQ (Frequently Asked Questions)

1. What is the Definition of a Chemical Reaction?

A chemical reaction is referred to as the process in which a set of chemical substances tend to react with one another, which, as a result, leads to their conversion from one form into several other different forms. The initial substances that are used the reaction are together known as reactants, whereas the final substances that get formed after the reaction has taken place are referred to as products. The chemical properties, in general, of both the reactants and the products, tend to differ from each other. Depending on whether the reaction gets initiated in the presence of energy or without the energy, it is divided into two different types, which is the spontaneous reaction which occurs on its own and the non-spontaneous reaction which needs energy to activate its process.

2. What are the Different Chemical Processes in Everyday Life?

There are so many different chemical process and changes that keep occurring around us in our day to day life. If we look around us, almost every substance is a chemical, and hence, we often notice these reactions on a daily basis. Given below are some of the examples of the chemical reactions in our daily life:

  1. Photosynthesis

  2. Combustion

  3. Aerobic cellular respiration

  4. Anaerobic respiration including the process fermentation

  5. Metathesis reactions, for example, vinegar and baking soda

  6. Oxidation which includes rusting

  7. Digestion

  8. Electrochemistry which includes the chemical batteries

  9. The several soap and detergent reactions

  10. Cooking

  11. Acid-base reactions

  12. Fireworks

  13. Electroplating of the metals

  14. Rotting of food

  15. Disinfecting the different surfaces and contact lenses

  16. Bleaching

  17. The leaves changing their colour with different seasons

  18. Drugs

  19. Hair colouring process
