1) How does temperature affect solubility of oxygen in water? High temperature affects solubility of oxygen in water by accelerating microbial growth, and increasing  the demand on dissolved oxygen. Microbial growth increases because enzymes work most effectively at  optimal temperatures. The optimal temperatures of enzymes in mitochondria are thus activated, and so more  oxygen is in a higher demand. 2) Design an experiment to measure the effect of salinity on the solubility of oxygen to water. What variables

Unformatted text preview: would you need to control? I would have water in the three BOD bottles like in Lab 12A, but each sample would be at the same temperature. Each bottle would have a different salt concentration. One bottle would have no salt. And the other would have dramatically different salt concentrations. Then I would repeat steps 3 and 4 from the previous lab procedures and figure out the oxygen saturation of each sample using the Nomograph given....
