A seed crystal will initiate crystallization in a _____________ solution. AunsaturatedBcrystalizedCsaturatedDsupersaturated

To determine which type of solution a seed crystal will initiate crystallization in, let’s analyze each option:

1. Unsaturated Solution: This is a solution that has not reached its maximum solute capacity. Adding a seed crystal would not lead to crystallization, as the solution can dissolve more solute.

2. Crystallized Solution: This term generally refers to a solution that has already formed crystals. In this case, adding another seed crystal would not be effective, as the solution is already at a solid state.

3. Saturated Solution: In a saturated solution, the maximum amount of solute has been dissolved at a given temperature. Adding a seed crystal may not lead to further crystallization as the solution is balanced with dissolved and undissolved solute.

4. Supersaturated Solution: This type of solution contains more dissolved solute than it would typically hold at equilibrium, often created by heating a saturated solution and then allowing it to cool. Adding a seed crystal here can initiate crystallization as the excess solute will begin to form solid crystals around the seed.

Final Answer

A seed crystal will initiate crystallization in a supersaturated solution.
