A solution has a little solid left at the bottom and the liquid above is clear. What does this indicate?
Answer and explanation
Correct answer: The solution is probably saturated
If a solid remains at the bottom while the liquid phase is clear, the liquid may have reached its dissolving limit at that temperature. The undissolved solid is evidence that additional material is not entering the solution under the present conditions, so the solution is probably saturated. The observation alone should be interpreted with care, but it certainly does not indicate pure water or conversion of all solid into gas.
