differences between a saturated and unsaturated solution (4 points each)
Answers
Saturated Solutions:
A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent. The additional solute will not dissolve in a saturated solution.
The amount of solute that can be dissolved in a solvent to form a saturated solution depends on a variety of factors.
→Solubility increases with temperature. For example, you can dissolve much more salt in hot water than in cold water.
→Increasing pressure can force more solute into solution. This is commonly used to dissolve gases into liquids.
→The nature of the solute and solvent and the presence of other chemicals in a solution affects solubility.
For example, you can dissolve much more sugar in water than salt in water. Ethanol and water are completely soluble in each other.
Unsaturated Solution:
An unsaturated solution is a chemical solution in which the solute concentration is lower than its equilibrium solubility. All of the solute dissolves in the solvent.
→When a solute (often a solid) is added to a solvent (often a liquid), two processes occur simultaneous.
→Dissolution is the dissolving of the solute into the solvent. Crystallization is is the opposite process, where the reaction deposits solute.
→In an unsaturated solution, the rate of dissolution is much greater than the rate of crystallization.
