Question

solute crystals are added to a solution until they begin to sink to the bottom of their container. the solution is then heated, and many more solute crystals dissolve. which term best describes the solution immediately after it was heated?
o saturated
o unsaturated
o concentrated
o supersaturated

Explanation:

A saturated solution has the maximum amount of solute that can dissolve at a given temperature. When heated, more solute dissolves, which means it was not at its maximum - capacity for the new (higher) temperature yet. An unsaturated solution can dissolve more solute. A concentrated solution just has a large amount of solute relative to the solvent but doesn't necessarily have a relationship with temperature - induced solute dissolution like this. A supersaturated solution has more solute than it should theoretically hold at a certain temperature and is unstable. Since more solute dissolved upon heating, it was unsaturated at the higher temperature.

Answer:

unsaturated
