Concept explainers
Interpretation:
Latitude with lowest average dissolved oxygen values have to be found.
Concept introduction:
Solubility can be defined as maximum amount of solute that can dissolve in known amount of solvent at a given temperature and pressure.
With increasing the temperature, the solubility of a gas in liquid decreases.

Answer to Problem 128A
Average dissolved oxygen values are lowestnear the equator.
Explanation of Solution
Near the equator, the solubility of a gas in liquid is lowest. The temperatures of surface water are highest near the equator. At higher temperatures, the escaping tendency of the gaseous particle from the solution increases results in the solubility of the gaseous solute decreases.
