Explain two chemical ways to detect impurities in water.
Answers
Explanation:
Add chlorine to water
Add bleaching powder in water
Answer:
The kits usually come with a package of strips that contain reactants that change color to indicate the presence of various contaminants in your water. The First Alert WT1 Drinking Water Test Kit (about $15) tests for bacteria, lead, pesticides, nitrites/nitrates, chlorine, hardness, and pH.
detection of inorganic impurities:
take a sample of water and check it for ionization radiation using sensitive dosimeter, if there is the slighest signal, the sample is radioactive. Check the space in which measurement of H2O radioactivity will be done.
2. evaporate the exact volume of the water using rotary vacuum evaporator /t 80-90 oC/, weight it and look for some specific reactant sensitive for uranium /235 and 238/, radium, thorium 232, rubidium 87 or kalium 40, etc. I do not know any. Check the activity of dry residuum, also.
3. If your results are positive and exceeding the permitted level, a.g. for drinkable water, the best solution is to address an institution responsible for public helth...or for nuclear energy.
