The solubility of oxygen in water is a function of the water temperature. Let S represent the solubility of O2 as millimoles of O2 per liter of water. Let T be temperature in ‘C. Use the following data to obtain a curve t for S as a function of T. Use the t to estimate S when T = 8°C and T = 50°C.
T (°C) S …………… (mmol O2 /L H2O)
5 …………………… 1.95
10 …………………… 1.7
15 …………………… 1.55
20 …………………… 1.40
25 …………………… 1.30
30 …………………… 1.15
35 …………………… 1.05
40 …………………… 1.00
45 …………………… 0.95
