The contaminants that pose immediate health risks and the contaminants that can be eliminated by boiling are to be stated. Concept Introduction: Water is a common liquid that is present on the Earth. It is also known as universal solvent. It can dissolve a wide range of organic and inorganic solutes. Water is vital for the existence of all living animals. Without water, no life form can exist, it constitutes an important part of rivers, lakes, streams, clouds, snow and ice. Water is truly an unusual molecule such that being a low molar mass compound, it exists as a liquid at room temperature and has an anonymously high boiling point. Ice floats on water because it has a lower density than water. Water contains some unwanted particles which can lead to diseases and other hostile effects on human health. Numerous types of micro-organisms such as bacteria are present in water, which contaminate the water. Biological contaminants: Some microbes can live in water and can cause various diseases like cholera, dysentery, and so on. Two examples of such microbes are Giardia and Legionella. Inorganic contaminants: Some inorganic molecules can dissolve in water and make it impotable (not suited for drinking). Two examples of such molecules are Nitrates and Asbestos. Organic contaminants: Some organic molecules can dissolve in water and makes it impotable (not suited for drinking). Two examples of such molecules are chlorohydrocarbons (volatile) and ethylbenzene (non-volatile). Radioactive contaminants: Some radioactive elements can dissolve in water and make it impotable (not suited for drinking). Two examples of such elements are Uranium and Radium. Contaminants that pose immediate health risks are the biological contaminants and inorganic contaminants because they get immediately dissolved in blood and starts reacting with it. Contaminants that can be eliminated by boiling are the biological contaminants because the microbes can be killed by increasing the temperature.

" is The structure of the bicarbonate (hydrogen carbonate) ion, HCO3-, HCO3 best described as a hybrid of several contributing resonance forms, two of which are shown here. HO :0: :Ö: HO + Bicarbonate is crucial for the control of body pH (for example, blood pH: 7.4). A more self-indulgent use is in baking soda, where it serves as a source of CO2 CO₂ 2 gas, which gives bread and pastry their fluffy constituency. (i) Draw at least one additional resonance form. = (ii) Using curved "electron-pushing" arrows, show how these Lewis structures may be interconverted by movement of electron pairs. (iii) Determine which form or forms will be the major contributor(s) to the real structure of bicarbonate, explaining your answer on the basis of the criteria in Section 1-5.
