Solution Equilibrium
1. A solution that is at equilibrium must be
1) concentrated
3) saturated
2) dilute
4) unsaturated
2. Some solid KNO 3 remains at the bottom of a stoppered
flask containing a saturated KNO 3(aq) solution at 22°C.

crystallization.
2) The rate of dissolving is greater than the rate of
crystallization.
3) The concentration of the solid is equal to the
concentration of the solution.
4) The concentration of the solid is greater than the
concentration of the solution.
