Explanation:
Answer:
Most solids in solution exhibit a general trend of increasing solubility with increasing temperature.
A seed crystal may be added to a supersaturated solution to precipitate excess solute.
Explanation:
For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions(Lumen Learning).
When a seed crystal is added to a supersaturated solution, excess solute begin to precipitate because the seed crystal now furnishes the required nucleation site where the excess dissolved crystals now begin to grow.
