Which is the condition, unrelated to quantities, that indicates that the rate going into solution is equal to the rate coming out of solution?

1. Dilute
2. concentrated
3. Unsaturated
4. Saturated E. Supersaturated

Correct answer: Saturated E. Supersaturated

Solution

A saturated solution is in dynamic equilibrium: solute dissolves and comes out of solution at equal rates. That means the amount dissolved stays constant, which matches the condition described.
