Our entire universe is made up of matter which is constantly changing forms and evolving into other forms of energy. Chemistry is defined as the study or science of this ever changing matter. Or chemistry is essentially the study of materials and the development of new materials for the betterment of humanity. We use chemistry from the beginning of the day till its end, the toothpaste we use to brush our teeth is made of abrasives, fluoride, and detergents. It is a very simple fact that chemistry plays an important role in every person’s daily activities from the moment we’re born. The role of chemistry usually begins first thing each morning. Most people wake up to an alarm or radio. These common household items contain batteries, which make them very chemically dependent. These batteries contain positive and negative electrodes. The positive electrode consists of a carbon rod surrounded by a mixture of carbon and manganese dioxide. The negative electrode is made of zinc and certain chemical reactions takes place which in turn produces electrical energy which finally drives the alarm or radio. The two significant contributions made by chemistry towards our lifestyle is the protection of our health and hygiene. The purification our water by process of chlorination, dental cleanliness from toothpaste, sterilization, the control and the cure of disease are all a part of daily living discovered and created by chemistry. These discoveries make up a major component for the protection of our health and hygiene and are vital for the future existence of mankind.
The ideal water for humans is hard water. Hard water is healthy as it consists of calcium, Ca2+, and magnesium, Mg2+, ions. Ca2+ is needed in the formation of bones and is important in the clotting of the blood and regulating the heart beat. Mg2+ is needed for making protein and for passing impulses along nerve cells. The chlorination of water for...
