Unit 1 – Some Basic Concepts Of Chemistry

Science can be viewed as a continuing human effort to systematize knowledge for describing and understanding nature. Curd formation from milk, formation of vinegar from sugarcane juice on keeping for prolonged time and rusting of iron are some of the examples of changes which we come across many times. For the sake of convenience, science is sub-divided into various disciplines: chemistry, physics, biology, geology, etc. The branch of science that studies the preparation, properties, structure and reactions of material substances is called chemistry.   DEVELOPMENT OF CHEMISTRY Chemistry, as we…
