Table sugar In each measurement you mix known masses of the salt and the water. If the molecule or ion happens to collide with the surface of a particle of the undissolved solute, it may adhere to the particle in a process called crystallization. Salt is soluble in water too. State whether sodium chloride is a molecular element, molecular compound, or ionic compound. to a solvent (e.g. A solid is stirred into a liquid and dissolves. Hence water is better able to decrease the electrostatic attraction between \(\ce{Li^{+}}\) and \(\ce{Cl^{-}}\) ions, so \(\ce{LiCl}\) is more soluble in water than in acetone. You want to create the sweetest chocolate bar by maximizing the sugar concentration. In contrast, adding a seed crystal to a saturated solution reestablishes the dynamic equilibrium, and the net quantity of dissolved solute no longer changes.
