Drinking too much water can lead to hyponatremia, water intoxication, water poisoning and death Liquid H2O is the sine qua non of life.   Making up about 66 percent of the human body, water runs through the blood, inhabits the cells, and lurks in the spaces between. At every moment water escapes the body through sweat, urination, defecation or exhaled breath, among other routes. Replacing these lost stores is essential but rehydration can be overdone. There is such a thing as a fatal water overdose.   ...

A 2007 study finds that discharge of untreated sewage is the single most important cause for pollution of surface and ground water in India. There is a large gap between generation and treatment of domestic waste water in India. The problem is not only that India lacks sufficient treatment capacity but also that the sewage treatment plants that exist do not operate and are not maintained.[1] The majority of the government-owned sewage treatment plants remain closed most of the time due to improper...

how hydrogen bonding occurs between water molecules, and relate this and other properties of water, to the roles of water in living organisms. Water is a very small molecule, consisting of two hydrogen atoms covalently bonded to an oxygen atom. However the electrons shared are not done so equally, oxygen is more electronegative and has a firmer hold on the electrons and pulls them slightly towards its nucleus. Due to this, the charge across the molecule of water is not equally distributed, and the...

Properties of Water Introduction: Water's chemical description is H2O. As the diagram to the left shows, that is one atom of oxygen bound to two atoms of hydrogen. The hydrogen atoms are "attached" to one side of the oxygen atom, resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side, where the oxygen atom is. This uneven distribution of charge is called polarity. Since opposite electrical charges attract, water molecules...
