Saturated, Unsaturated & Supersaturated Solutions Solution, in which the concentration of solute is that determined by its solubility (at given temperature) is called SATURATED solution. One cannot add more solute to such a solution. We also say that a saturated solution is in equilibrium with pure solute: If we add solid Nacl to an already saturated solution of NaCl, that solid remains in equilibrium with dissolved Naci. Solution containing less solute than would be in the saturated solution, is UNSATURATED...

The saturation concentration of dissolved oxygen in freshwater can be calculated with the equation: In osf - -139.34411 +1.575701 x 10-6.642308 x 101.243800 x 1010 1-8.621949 x 10" 10101-8.621949 x 10 1 where, osf is the saturation concentration of dissolved oxygen in freshwater at I atm ( osf is in mg/liter); and Ta absolute temperature (K). According to this equation, saturation decreases with increasing temperature. For typical natural waters, the oxygen concentration ranges from 14.621 mg/liter at 0°C (273 K)...
