Document Summary

H2o and ethanol form hydrogen bonds both with themselves and with each other. The solubility of some solids as a function of temperature. The aqueous solubilities of most solids increase with increasing t, some decrease with t. Depends on the dissolution process being endothermic or exothermic. The solubility of some gases in water as a function of t at a constant pressure of 1 atm. The greatest gas solubility for a gas in solution is predicted under what conditions: By mass, its mg/kg or in solution, its mg solute/l solution. 1 ppm is like 1 inch in 16 miles or 1 second in 11. 5 days. 1 microgram/kg or 1 ug/kg by mass or 1 ug/l of solution. Some physical properties of solutions are different from those of the pure solvents. These all depend on the concentration of solute particles in solution, not on the identity of the solute.
