As growth continues, the endosperm matures into its cellular phase and deposits into the rind of the coconut meat. We need water for different purposes. Consequently, aqueous alcohol solution passing through bed of starchy or cellulose material would come out with lower concentration of water in the solution.s 1995). Name :-Deepesh kumar Class :-12TH A Roll no. Need of water Water is an important and essential ingredient in our quest for survival on this planet. Water is by nature more polar than organic compounds such as alcohols. This optical effect is due to refraction. Yellow precipitate indicates the presence of K+. In soil correlation work, the use of pH in CaCl 2 is preferred because the measurement will be less dependent on the recent fertilizer history. Chemical analyses of water generally report the total quantity of a particular element or ion without indicating its actual form in solution. Use test tube holder to hold the test tube. Prepare the paste of it with few drops of water rub and smell. Analytical methods routinely used can detect and measure all the natural elements and their inorganic compounds and a very wide range of organic chemical species using methods such as gas chromatography and mass spectrometry. To one part of the solution and add solid NH4Cland NH4OH in slight excess then add ammonium phosphate. We've updated our privacy policy so that we are compliant with changing global privacy regulations and to provide you with insight into the limited ways in which we use your data. Mother Nature keeps an orderly house. BOILING AND DISTILLATION 3. The Drinking Water should be totally clean, pure and free of any disease causing MICROBES, and that's why it should be properly Treated and DISINFECTED before using it for drinking purpose. Class 12 CBSE 2017*2018. This is to certify that this Investigatory project has been submitted by Master Deepesh kumar of Class 12-A to the Chemistry department. There are less than 100 elements "in nature" and, by definition, they're all separate and distinct from one another. Table 4 will help you interpret the hardness parameters cited on your analysis. Water chemistry analysis is often the groundwork of studies of water quality, pollution, hydrology and geothermal waters . Part 3 will then describe how to use chemistry and ion exchange selectivity to solve certain treatment problems. No reaction. Download and Print or make a copy to your Mobile. METHODS OF PURIFYING WATER 1. For use in chemical thermodynamic calculations, the concentrations of par- ticipating reactants or products must be identified as specific solute species.
