A great many chemical reactions take place within aqueous solutions. Some solutes dissolve quite easily in water, while others do not dissolve very well at all. Some things may be very soluble, and yet the rate of the dissolving process is very slow. The ability of a solute to dissolve is affected by external factors like temperature and pressure. Solutions have different physical properties from pure solvents. The amounts of solute contained within solutions must be measured so that reactions can be followed quantitatively. The solutions in the picture have been prepared in a type of flask called a volumetric flask. Using a volumetric flask allows chemists to know precisely the concentration of the solution that has been prepared. In this chapter, you will learn about many aspects of solutions, including their formation and their physical and chemical behavior.
