Water is the most abundant chemical substance in the world. It covers 70 per cent of the surface of the earth. It occurs in form of water vapour in the atmosphere and this may collect as cloud and later come down to the earth in form of rain. It is also present below the earth.

Water is a transparent and nearly colorless chemical substance that is the main constituent of Earth’s streams, lakes, and oceans, and the fluids of most living organisms. Its chemical formula is H2O, meaning that its molecule contains one oxygen and two hydrogen atoms, that are connected by covalent bonds. Water strictly refers to the liquid state of that substance, that prevails at standard ambient temperature and pressure; but it often refers also to its solid state (ice) or its gaseous state (steam or water vapor). It also occurs in nature as snow, glaciers, ice packs and icebergs, clouds, fog, dew, aquifers, and atmospheric humidity.

Water is very important to all kinds of plants and animals even to humans. Not only is water used all over the world in vast quantities for drinking purposes, but it is used in  even greater quantities for washing, bleaching, dyeing, cooking, raising steam to drive engines and turbines to generate electricity and as a solvent in industrial processes. Water plays an important role in the world economy. Approximately 70% of the freshwater used by humans goes to agriculture. Fishing in salt and fresh water bodies is a major source of food for many parts of the world. Much of long-distance trade of commodities (such as oil and natural gas) and manufactured products is transported by boats through seas, rivers, lakes, and canals. Large quantities of water, ice, and steam are used for cooling and heating, in industry and homes. Water is a good solvent for a wide variety of chemical substances; as such it is widely used in industrial processes, and in cooking and washing. Water is also central to many sports and other forms of entertainment, such as swimming, pleasure boating, boat racing, surfing, sport fishing, and diving.

 

 

Sources of water

  1. Rain Water– This is the purest form of natural water because it is formed as a result of the condensation of water vapour in the atmosphere. Rain water contains small impurities like gases such as CO2 from the air and also dust particles present in the air. Dissolved oxygen and nitrogen will always be present in rain water. After electric storms during which oxygen and nitrogen react to form oxides of nitrogen, rain water may actually be an extremely dilute solution of trioxonitrate(V) acid.
  2. River Water– Rivers are used extensively for sewage disposal. River water contains a lot of dissolved air, mineral salts, bacteria and organic remains. It is dirty and needs to be purified especially before drinking.
  3. Spring Water– Spring water is purer than River water. It contains a considerable amount of mineral salts but very little suspended impurities such a s dust and bacteria. It is good for drinking.
  4. Sea Water– This is the most impure form of natural water because impure water is consistently flowing into it and at the same time, purer water is constantly leaving it through evaporation. The main inorganic metallic salt present in sea water is Sodium chloride, but Magnesium, Calcium and Potassium salts are also present. Of all the solid impurities in sea water, the most important ones are Calcium tetraoxosulphate (vi) and Calcium hydorgen trioxocarbonate (iv).

 

Keeping sources of water clean

  1. Prompt repairs of burst water pipes
  2. Well should be covered
  3. Use clean bucket to fetch water from well
  4. Avoid dumping refuse into river
  5. Avoid using chemical for fishing in the river

 

Assessment

  • Mention four sources of water
