Solvent Properties . To point out that water existed on this planet long before life evolved is, of course, stating the obvious, but the uniqueness of water as the universal solvent is still not generally appreciated. Stir both the water and the ice-rock salt solution continuously. Can also be used for cleaning brushes, rollers, equipment parts and for flushing through spray lines and spray guns. The boiling point of the solvent should be low enough ( well below the melting point of the solute) such . Therefore, water is referred to as a , a substance capable of dissolving other polar molecules and ionic compounds. The water molecule results to be charged negatively near the atom of oxygen and positively near the atom of hydrogen. The great solvent properties of water are due to its ability to form dipoles and hydrogen bonds. Water is a small solvent, occupying about 0.03nm3 per molecule in the liquid state at room temperatureandpressure,yetitishighlycohesivebecause of the strong intermolecular interactions (hydrogen bonds, or H-bonds) between the oxygen and hydrogen Charged substances in Water. •SWBAT explain how water's properties are essential for life on earth.
