    What is Dissolving? Some substances dissolve when mixed with water and will seem as if they have disappeared. However, they are still there, but the particles are so small you can no longer see them. This is because the solute breaks up from a larger crystal of molecules into much smaller groups or individual molecules. The substance mixes with water to
