a) In the sediments at the bottoms of ponds and lakes, there is often absolutely no O2 at depths of 0.5 cm or more, even if the water above is rich in O2. How is this possible?
b) The absorption coefficient of O2 in seawater at 0 °C is 1.7 mmol/L. What is the concentration of O2 if the O2 partial pressure is 0.1 atm? Express your answer first in mmol/L, then in ml/L.
c) The hemoglobin in mammalian blood is usually thought of simply as increasing the amount of O2 that can be carried by each litter of blood. Explain how the presence of hemoglobin in the blood also makes possible the rapid uptake of O2 by the blood as it flows through the lungs.
