It is noted that a suspension, which is another kind of liquid mixture, greatly differs from a solution. A suspension may be demonstrated by placing some sand in a glass of water and then stirring the mixture violently for a moment. If this is done, the two substances mix but no solution is effected. The particles of sand, being larger than any of particles of the true solution, mix for a while, but since they move about less freely, they finally settle on the bottom when agitation of the mixture ceases.
