MAJOR FIELDS/AREAS THAT JUSTIFY THE IMPORTANCE OF CHEMISTRY
The Importance of Chemistry in agriculture, extraction of metal, cosmetics, health, fuels, textiles, and electronics
1.0 Agriculture
Chemistry plays a crucial role in agriculture, which is vital for our food supply. As the population grows, farmers need to produce more food to meet the demand. Chemistry helps by providing:
- Fertilizers: Enhance soil fertility, allowing crops to grow better and increase yields.
- Insecticides: Protect crops from harmful insects that can destroy plants.
- Pesticides: Keep pests at bay, safeguarding crops from damage and loss.
- Fungicides: Prevent the growth of fungi that can harm crops and reduce food production.

These chemical solutions enable farmers to improve the quality and quantity of food produced, ensuring that there is enough to meet society’s needs. Thus, the importance of chemistry in agriculture is evident in its ability to help farmers grow more and better food.
2.0 Extraction of Metals
Man needs a variety of metals such as iron, gold, steel, brass, aluminum, copper, and silver for making various items like – utensils, vehicles, tools, machines, buildings, factories, etc.
Metals are mined from the earth, but it does not offer them in their pure form for direct use. It gives us in the form of ores. Ore is a type of rock that contains particular metals along with several other substances like clay, sand, etc. Thus, we need to extract pure metals from its ores. Chemistry helps us in this extraction. The importance of chemistry in the process could be understood by the fact, that all the steps required for carrying out extraction are developed using knowledge of chemistry.
For example, if you want to make a wire of copper, then first you have to find a copper ore and from it, you will extract pure copper for making wire. An ore of copper contains a mineral called copper sulfate. Copper sulfate dissolves in water to form an aqueous solution which, when reacted with pure iron, forms pure copper.
The crane excavates metal ores, from which metal will be extracted using a process laid down by chemistry.
3.0 Importance of Chemistry in Cosmetics
Chemistry is fundamental to the development of cosmetics, which are essential for grooming and personal care. From powders and creams to soaps, shampoos, lipsticks, and perfumes, every cosmetic product we use is crafted through the principles of chemistry. Chemists spend years researching and observing various substances to formulate products that are safe, effective, and appealing. The importance of chemistry in cosmetics is evident, as it not only enables the creation of these products but also drives continuous innovation, improving their quality and effectiveness. Without the knowledge of chemistry, the diverse range of grooming and beauty items we enjoy today would not exist, underscoring its significance in our daily lives.
4.0 Importance of Chemistry in Medicines
The importance of medicines is well understood, as they are essential for keeping us healthy and disease-free. However, without chemistry, medicines would not exist. Chemistry is crucial in conducting medical tests to diagnose health issues and in the discovery of new treatments.
Medicines the result of Chemistry
To illustrate the importance of chemistry in medicine, consider this example:
In ancient times, patients suffered severe pain during surgery because they remained fully conscious. Today, however, surgeons use anesthesia, which allows patients to be unconscious and pain-free during operations. The discovery of anesthesia is a direct result of advancements in chemistry. This example highlights how chemistry plays a vital role in improving medical practices and patient care.

5.0 Fuels
Chemistry plays a crucial role in providing us with various types of fuels that are essential for daily life. Fuels are important because they release a large amount of energy when burned, powering everything from vehicles to household appliances. Chemistry helps in the extraction and refining of these fuels from crude oil, a complex mixture of different substances. Through chemical processes, we obtain different fuels that serve specific purposes:
- Petrol and CNG: Used in light vehicles like cars and motorcycles.
- Diesel: Powers heavy vehicles and machinery, including trucks, buses, ships, cranes, and generators.
- Kerosene: Used as fuel in airplanes.
- LPG: Commonly used for cooking food in households.
Without chemistry, the separation and production of these fuels from crude oil would not be possible.
Chemistry provides fuel for transportation
6.0 Textile
Chemistry plays a significant role in the textile industry by enabling the creation of artificial fibers like nylon and rayon, which serve as alternatives to natural fibers such as cotton and silk. These synthetic fibers offer durability, affordability, and versatility in clothing. Additionally, chemistry is essential in producing dyes that add vibrant colors to fabrics, allowing for a variety of clothing options. Without chemistry, we would be forced to wear clothes in their natural, uncolored state. Thus, the importance of chemistry is evident in the colorful and diverse range of textiles available today.
