A short computer animation illustration how positive and negative ions in a solid ionic compound dissolve in water might be used to accompany the dissolving salts in water demonstration.

Several ionic salts (calcium chloride, ammonium nitrate, potassium chloride, magnesiium sulfate, lithium chloride, anhydrous sodium acetae, anhydrous sodium carbonate) are dissolved in water in a calorimeter. A thermomters measures the intitial temperature of the water and the final temperature of the resultant solution. Dissolving ionic salts in water can be used to illustrate formation of Solutions, Enthalpy, Lattice Energy, etc.

Water and Hexane are the solvents. Iodine and potassium permanganate are the solutes. Iodine dissolves in hexane. Potassium permanganate dissolves in water.

When a current is applied to an aqeous solution, strong electrolyte solutions light up a light bulb, weak electrolyte solutions dimly light a bulb, and nonelectrolyte solutions do not light a bulb.
