  2. 2. A solution is formed when a solutedissolves in a solvent to form a single phase that appearsuniform throughout.
  3. 3. • A solution is clear.• In a solution, the particles are too small that they cannot be seen by unaided/naked eye.• The solute from the solution cannot be separated by filtration.• The solution does not allow beam of light to scatter.• A solution is a homogenous mixture• A solution is stable.• As temperature increases, the solubility (of solids) increases.• All solutions have a solvent and at least one solute
  4. 4. • There is a limit to how much solute will dissolve in a given volume of solvent at a given temperature. Saturated solution = when that limit has been reached & no more solid can dissolve.• White solids become invisible when dissolved in clear solvents.• Non-white solids give their color to their solvents.• You can separate dissolved solutes from solution by evaporating away the liquid solvent.• In some solutions, volume decreases as the solute dissolves.
  5. 5. • Mass is conserved when solutes dissolve in solvents.• As you increase the amount of solvent, the amount of solute that can dissolve will also increase at the same rate.• A solution has a constant density throughout.• Solutions are transparent (light can travel through them without being "blurred")
  6. 6. Gaseous Solution- includes gases or vapors dissolved in one another. Two or more gases can form a solution. Air is an example of a gaseous solution. When dry is made up of oxygen gas dissolved in nitrogen gas.Liquid Solution-contain a liquid solvent in which gas, liquid, or solid is dissolved. Water is the most common liquid solution. Many things can be dissolved in it. Table salt is an example of a solid dissolved in a liquid. A liquid and a gas can also be dissolved in a liquid solution. Solid Solution-is a mixture of solids spread equally throughout one another. Metal is an example of a solid solution at room temperature.
  7. 7. Solubility is the maximum amount of solutethat can dissolve in a given amount of solvent at a certain temperature. Saturated – maximum amount of solute dissolved by a given amount of solvent. Unsaturated – when it contains less solute than the maximum amount it can dissolve at a given temperature.
  8. 8.  The particles of solute are the size of individual small molecules or individual small ions. One nanometer is about the maximum diameter for a solute particle. The mixture does not separate on standing. In a gravity environment the solution will come apart due to any difference in density of the materials in the solution. The mixture does not separate by common fiber filter. The entire solution will pass through the filter.
