Chemistry is the science that studies the composition and structure of matter, its properties, its transformations and energy involved in these transformations. It sees the changes happening in the field during the so-called chemical reactions and serves to produce economically valuable resources and to improve our quality of life.
Chemistry is present and intervenes in all the material needs of man: in the preparation and conservation of food, in the materials that form the objects that surround it, in the elaboration of medicines, etc.
Applications of Chemistry
Chemistry is found everywhere: in the photosynthesis of plants, in the DNA of our cells, in medicines, in the colour of our clothes, in the elaboration of fuels ... It would be possible to affirm that Chemistry is one of the sciences what has allowed society to advance and what has facilitated and improved people's lives. Can you imagine the world without vaccines, without computers or without means of transport like the car? To understand the multiple applications that Chemistry has, we can look at the different disciplines that exist within this science, and that are grouped according to the type of study or the subject that they analyse.
Classification of the different branches of Chemistry
In an attempt to classify the different branches of Chemistry we must mention:
· Organic chemistry: studies the compounds that contain atoms with carbon / hydrogen bonds, such as hydrocarbons, polymers or proteins. It covers all-natural elements and organic tissues. It provides us with solutions to improve our quality of life in areas such as hygiene or health.
· Inorganic chemistry: studies the creation, structure, construction and chemical reactions of inorganic elements and compounds, that is, those that do not contain carbon / hydrogen bonds, such as metals, minerals or ceramic materials. For example, fibre optic, concrete or electronic chips are applications of inorganic chemistry.
· Biochemistry: Study the substances present in living organisms, such as plants, animals, microorganisms or humans.
· Chemistry-physics: studies the matter and its transformations through the application of physical knowledge such as movement, time, energy, forces, etc.
· Analytical chemistry: its purpose is the study of the chemical composition of a material or sample, through different laboratory methods.
· Chemical engineering: branch of engineering that is in charge of the development of industrial processes to carry out the chemical and physical transformations of the matter and the design of new materials whose elaboration requires sophisticated physical and chemical transformations of the matter.
· Astrochemistry: study the composition of the material elements found in the universe, such as stars, planets or comets.
· Electrochemistry: analyses the relationship between chemical reactions and electricity.
· Pharmaceutical chemistry: Study of molecules and their synthesis to develop medicines with the aim of combating or alleviating diseases.
· Environmental chemistry: studies the chemical processes that take place in the environment (in the soil, the water of seas, rivers, lakes and oceans and in the atmosphere ...), as well as the impact of human activities on our environment.
Only with the aforementioned concepts can we get an idea of the many applications of this science in industry and in society. For example, for the development of new fabrics or materials to increase sports performance, for the creation of more environmentally friendly fuels or cosmetic products for people with high sensitivity to the skin.
