Water H2O constitutes of two hydrogen atoms and a single oxygen atom.The hydrogen atoms are linked to the oxygen atoms by covalent bonds. When water molecules interact with each other, the positively charged region (hydrogen atom) of one water molecule forms a weak hydrogen bond with the negatively charged region (oxygen atom) of a second water molecule [1].
The basis of life, humans contain around 40 litres of water.
Many diseases are associated with water, for example excess water (hyperhydration), not enough water (dehydration) and many microorganisms use water as a form of transport and spread through water, e.g. Cholera.
For example Tchaikovsky is thought to have died of cholera: On 2 November 1893, he drank a glass of unboiled water. A few hours later, he had diarrhoea and started vomiting. The following day anuria occured. He lost consciousness and died on 6 November [2].
