H,O Lab Time: 1:30 Pm H,0 + COH2 CozHcozt : PH - AR+Neo Air 1. Knowing that these 2 molecules are always floating in the air, hypothesize why your distilled water ( which indeed was pure when put in the container and therefore should have been pH 7), instead had a pH between 5 and 6 (i.e. acidic, not neutral). 2. Hypothesize why the addition of sucrose did not change the pH of distilled water (a big hint to the answer is in the lab section on Acids & Bases).
Exponential Decay A. Dehydration Biological Half-Life: "The time required for half the quantity of a drug or other substance deposited in a living organism to be metabolized or eliminated by normal biological processes." The biological half-life of water in a human is 7 to 14 days. This means that it takes one to two weeks to lose half of the water in your body. Why such a broad range? Because the half-life of water can be dramatically altered by a person's environment and behaviour. What are some factors that would affect your rate of dehydration?

Assessment : Short Quiz True or False 1. Polarity of water is due to the more electronegative hydrogen and less electronegative oxygen. 2. Water can make hydrogen bond with its own molecule only. 3. Droplets of water is due to cohesion. 4. Surface tension is due to adhesion. 5. Hydrogen bonding is stronger than covalent bonding & ionic bonding.
