On this Wikipedia the language links are at the top of the page across from the article title. When a solute is mixed with a solvent, there are three possible outcomes: If the solution has less solute than the maximum amount it is able to dissolve (the solubility), it is a dilute solution. When first appears, what fraction of CI- the originally present remains in solution? We store cookies data for a seamless user experience. Thus, s=21[F ]. Good spectral range 4. A saturated solution of BaF2 at 25C is prepared by equilibrating solid BaF2 with water. The rate of solution refers to how quickly a substance dissolves, and is separate from solubility.
