Evaporation happens when water molecules move fast enough to break away from a solution and move into the air. When a solution evaporates, the water goes into the air but the solid is left behind.

For example, copper sulfate is soluble in water – its crystals dissolve in water to form copper sulfate solution. During evaporation, the water evaporates away leaving solid copper sulfate ...

Predicted evaporation times for given solutions were calculated and cross-checked for accuracy against experimental data. The predicted evaporation time for every water-organic solvent mixture was ...
