Question
Chapter 20, Problem 46SCQ
Interpretation Introduction
Interpretation: The advantages and disadvantages of different methods used to disinfect drinking water are to be given.
Concept introduction:
Water purification can be done using various methods which possess both advantages and disadvantages.
Disinfection of water can be done using powerful oxidizing agents like chlorine, ozone or sodium hypochlorite.
Disinfection of water leads to the elimination of pathogens which are responsible for spreading diseases like typhoid, cholera.

1) In lab you are given 4 bottles, each containing about 5 grams of a white substance. Near the bottles are four labels indicating each bottle contains a high purity substance. Assume these labels belong to the bottles and that each bottle contains a single substance.
The four bottles contain glucose (C6H12O6), sodium chloride (NaCl), aluminum oxide (Al2O3), and zinc sulfate (ZnSO4).
Using your knowledge of solubility rules and electrolytic behavior, describe tests that you could conduct to determine which label belongs to which bottle. For these tests you may only use DI water, an aqueous solution of barium nitrate, and a conductivity tester to identify the substance in each of the bottles. Give the results you would expect for each test.
Ethanol is metabolized in most people at a constant rate of about 120mg per hour per kg body weight, regardless of its concentration. If a 70kg person were at twice the legal limit (160mg/100ml), how long would it take for their blood alcohol level to fall below the legal limit?
Make a conclusion about the experiment of
• water & baking soda
• water & salt
• water & sugar
• water & powder detergent
