What effect (increase/decrease) would you expect each of the following to have on the p50 of hemoglobin? increase/decrease (a) a drop in the ph of blood plasma from 7.4 to 7.2. increase/decrease (b) a decrease in the partial pressure of co2 in the lungs from 6 kpa (holding one’s breath) to 2 kpa (normal). increase/decrease (c) an increase in the 2,3-bpg level from 5 mm (normal altitudes) to 8 mm (high altitudes). increase/decrease (d) an increase in co from 1.0 parts per million (ppm) in a normal indoor atmosphere to 30 ppm in a home that has a malfunctioning or leaking furnace.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
