What is Water?
Chemically a molecule of water is composed of two hydrogen atoms and one oxygen atom held together by covalent bonds. Water is precious to man’s existence as it is needed in agriculture, sports, industry, and domestic affairs. Water may be hard or soft. Hard water is not good economically as more soap is needed to form lather. When water is free from mineral salts, such water is called soft water as it dissolves soap quickly.
