INTRODUCTION
The principles of chemistry have been used for the benefit of mankind. Think of cleanliness — all the materials like soaps, detergents, household bleaches, toothpaste, etc. will come to your mind: all these are products of chemistry. Take a look at the beautiful clothes — immediately chemicals of the synthetic fibres used for making clothes and chemicals giving colours to them will come to your mind: these again are obtained from chemistry. Food materials — again a number of chemicals about which you have learnt in the previous Unit will appear in your mind. Of course, sickness and diseases remind us of medicines — again chemicals. Explosives, fuels, rocket propellents, building and electronic materials, etc., are all chemicals. Chemistry has influenced our life so much that we do not even realise that we come across chemicals every now and then; that we ourselves are beautiful chemical creations and that all our activities are controlled by chemicals. In this Unit, we shall learn the application of Chemistry in the three most important and interesting areas, which are – medicines, food materials and cleansing agents.
