Front

Can solutions be separated by physical means?

Back

Yes, solutions can be separated by physical means such as evaporation or distillation.

Front

What is the relationship between surface area and the rate of dissolving?

Back

The greater the surface area of a solute, the faster it will dissolve in a solvent.
