Marie and calvin dissolved 10 grams of kno3 in 100 grams of water at 25oc. next they added 5 grams more. calvin told marie that they could continue to add solute until they reached 40 grams because the solution was still a) saturated b) semisaturated c) supersaturated d) unsaturated

 D) unsaturated

Explanation:

A) Saturated solution is defined as the solution in which no more solute particles can be dissolved in the solvent.

B) Semisaturated is defined as the solution in which half of the amount has been added and  another half has to be added for saturation.

C) Supersaturated solution is defined as the solution in which more amount of solute particles is present than the solvent particles.

D) Unsaturated solution is defined as the solution in which more solute particles can be dissolved in the solvent.
