If you put a solute in a solution x, the solution x will cool down and form a solid…The solution has been……saturated, unsaturated, supersaturated, concentrated, or dilute???

Supersaturated. The solution will form solids when it's supersaturated unless your raise the temperature, then it will dissolve.

Urite but i thought it needs some kind of trigger to form solids after cool down? No?

In lab, the recrystalization process requires you to scratch the beaker to speed up the process of forming crystals. But, it's not necessary. Temperature should be enough. You can do so by boil water then add salt to supersaturation and then pour the solution in a paper cup to form squares of salt crystal as it cools without scratching.

I watched this (and read my chem book) a couple weeks back and it really helped me visualize the concept.

according to the above video.... the addition makes a saturated solution....

so the solution has been satured?? by quenching the excess ions???
