Title
Solution diagram of closed container of molecules
Caption
In a solution, the molecules of solute (such as sugar) are randomly distributed among the solvent (often water) molecules.
Keywords
solution, solute, solvent, homogeneous, mixture

Title
Ionic compound dissolving in water
Caption
When sodium chloride - or any other ionic compound - dissolves in water, each ion becomes completely separated from the solid crystal and becomes hydrated (surrounded by water molecules). Notice the difference in orientations of water molecules that surround the hydrated ions.
Keywords
ionic compound, dissolve, solvent, solute, solution, hydrated

Title
Immiscible liquids
Caption
Oil floats on water as shown in the photo and the diagram. The two liquids are immiscible because the oil has large, nonpolar molecules that are not attracted to the polar water molecules as greatly as water molecules are attracted to one another. For these liquids, polarities are not alike.
Keywords

Title
Oxygen solubility versus pressure
Caption
The graph shows the solubility of oxygen in water at various pressures at a temperature of 25oC.
Keywords

Title
Preparing a solution with a given molarity
Caption
To prepare 1.00 L of a solution of specified molarity, (a) obtain the appropriate mass of solute, (b) transfer the solid to a 1.00-L volumetric flask that is partly filled with distilled water, (c) add enough water to fill the flask to the 1.00-L mark. Once the solution is thoroughly mixed, it is ready to be placed in an appropriately labeled bottle for laboratory use.
Keywords
solution, preparation, molarity, volumetric flask, distilled water

Title
Sieve model of osmosis
Caption
The sieve modle of osmosis holds that the semipermeable membrane has pores large enough to permit the passage of small solvent molecules such as water but too small to permit the passage of larger molecules. The net flow of solvent is through the memberane into the compartment that has the greater concentration of solute.
