Design an Experiment You are given a sample of a solid solute and three aqueous solutions containing that solute. How would you determine which solution is saturated, unsaturated, and supersaturated?
Interpretation:
Thedifferent types of solution needs to be characterized.
Concept introduction:
Solution is a homogeneous mixture of solute and solvent where a solute is fully dissolved in the solvent.
Depending upon amount of solute in a solution there are three types of solutions:
Unsaturated solution contains less amount of dissolved solute for a given temperature and pressure than a saturated solution.
Saturated solution is the solution when the maximum amount of solute is dissolved in the solution.
In supersaturated solution there is more solute present than a saturated solution at the same temperature. Increasing of temperature of the solution makes the excess solute to get dissolved and then cooled slowly.
Answer to Problem 117A
Upon addition of a tiny amount of solute to each solution, ifthe excess solute precipitates quickly or excess solute gets crystallized. So, the solution is supersaturated. If the excess solute does not dissolve or remains as it is. So, the solution is saturated. If the excess solute gets dissolved. So, the solution is unsaturated.
Explanation of Solution
Upon addition of a tiny amount of solute to each solution-
- If the excess solute precipitates quickly or excess solute gets crystallized. So, the solution is supersaturated.
- If the excess solute does not dissolve or remains as it is. So, the solution is saturated.
- If the excess solute gets dissolved. So, the solution is unsaturated.
