# Can someone help me please? I answered one of them but I would like someone to check it as well. For the other two, I honestly not sure how to do it. Thanks!

1)

A solution is saturated when the dissolved solid in the solution is in equilibrium with the undissolved solute. This can be checked by adding more ${\text{KNO}}_{3}$, the solute, into the solution.

• If it DOES dissolve, the solution is unsaturated.
• If it does NOT dissolve, the solution is saturated. This may be hard to notice.
• If the solution suddenly crystallizes (you'd be able to tell), then it is supersaturated and you had disturbed a metastable state.
