Chemistry in everyday life important points – Chemistry impacts our daily lives in the various ways, from the water we drink to the products we use, the food we eat, and the energy sources we rely on. Understanding these chemical processes enhances our knowledge and enables us to make the informed decisions about our health, environment, and everyday activities.
The chemical compounds present in the environment plays a very significant role in our day to day lives. If we look at our surroundings, everything which we see, is all chemistry.
Chemistry is the branch of science which deals with the investigation of the properties and changes of matter. From the way how our body exchanges oxygen to how our universe was created, all have a part of chemistry associated with it. The chemistry of all the compounds together leads to the formation of our environment.

NCERT Chemistry Class 12 Chapter 16 – 25 Chemistry in everyday life important points
There are 25 important points on chemistry in everyday life-
- Water, a vital substance for life, is composed of the two hydrogen atoms and one oxygen atom, making it a chemical compound (H2O).
- The food we eat undergoes various chemical processes during the process of digestion, including hydrolysis, which breaks down complex molecules into simpler ones.
- Medicines and drugs, such as aspirin or antibiotics, are the chemical compounds designed to interact with specific biological processes in our bodies.
- The production of the energy in our bodies is facilitated by chemical reactions, such as the oxidation of glucose during cellular respiration.
- The process of photosynthesis in the plants, where carbon dioxide and water are converted into glucose and oxygen using sunlight, is a fundamental chemical process.
- Cooking involves the various chemical reactions, such as the Maillard reaction, which gives food its characteristic flavor and browning.
- Cleaning agents, such as soaps and detergents, work by altering surface tension of water through chemical processes to remove dirt and stains.
- Rusting, a chemical reaction between the iron, oxygen, and water, causes the degradation of metals and is a common phenomenon in everyday life.
- The concept of pH, a measure of the acidity or alkalinity, is crucial in many everyday activities, such as cleaning, gardening, and swimming pool maintenance.
- Food preservation techniques, such as the canning or pickling, rely on chemical processes to inhibit the growth of microorganisms and prevent spoilage.
- Fire, a combustion process, involves rapid oxidation of a fuel source in the presence of oxygen, releasing heat, light, and various chemical byproducts.
- The production of the electricity in batteries is based on chemical reactions, such as the conversion of chemical energy into electrical energy through redox reactions.
- The concept of the oxidation and reduction (redox) reactions is essential in understanding various chemical processes, including combustion, corrosion, and electron transfer.
- Fertilizers are the chemical compounds used to enhance plant growth and productivity by providing essential nutrients needed for metabolic processes.
- Chemical reactions occurring in atmosphere, such as the formation of ozone or the greenhouse effect, play a significant role in climate change and air quality.
- Plastics, which are ubiquitous in the modern life, are synthetic polymers made through chemical processes, such as polymerization.
- The chemical processes involved in manufacture of textiles, dyes, and pigments contribute to the diversity of colors and patterns in the fashion industry.
- The process of fermentation, a chemical reaction carried out by the microorganisms, is responsible for the production of alcoholic beverages and bread-making.
- The analysis of the chemical compounds through techniques like spectroscopy or chromatography is crucial for forensic investigations and drug testing.
- Chemical reactions occurring in the batteries and fuel cells provide alternative sources of energy, reducing our dependence on fossil fuels.
- The development of the new materials, such as polymers or composites, through chemical engineering, has revolutionized industries like construction, automotive, and electronics.
- Chemical reactions and processes are involved in the wastewater treatment, ensuring the removal of pollutants before it is released back into the environment.
- Understanding chemical properties of substances is essential for safe handling and storage of hazardous materials, such as acids, bases, and toxic substances.
- The production of the cosmetics, perfumes, and personal care products relies on various chemical processes and formulations to achieve desired effects.
- Chemical analysis and quality control are crucial in the food and beverage industries to ensure the safety, authenticity, and nutritional value of products.
