Question

You are given a clear solution of KNO3. Using 3 – 4 sentences (in your own words) explain how you would determine if the solution is unsaturated, saturated or supersaturated @Cuanchi

Answer 1

I will think about cooling down the solution few degrees. If the solution is saturated or supersaturated some salt will precipitate.
If the solution is supersaturated just shaking the solution will induce salt precipitation.
Also if you add more KNO3 and the solution is saturated or supersaturated the added salt will not dissolve and precipitate. If the solution is unsaturated the salt will dissolve.
