* Supersaturated solution: This means the solution holds more solute than it normally can at a given temperature. It's in an unstable state, ready to crystallize.
* Seed crystal: This provides a nucleation site for the excess solute to crystallize upon. It acts as a starting point for the crystal growth.
* Crystallization: The excess solute in the supersaturated solution will quickly precipitate onto the seed crystal. This will continue until the solution reaches its saturation point, meaning it can no longer hold any more dissolved solute at that temperature.
Therefore, adding a seed crystal to a supersaturated solution causes crystallization, leading to a saturated solution with excess solute precipitated out as crystals.
