precipitation?

Question

You may observe a precipitate when

* A crystal of solute is added to a supersaturated solution.

* Excess solute is added to a saturated solution.

* The solute does not dissolve in the solvent.

* All of the above.

* None of the above

Answer 1

I think "precipitation" means that solid comes out of a solution, instead of "does not dissolve". Therefore, my choice is "A crystal of solute is added to a supersaturated solution"
