to water sugar crystals right into water and stir, and the sugar will dissolve. Save pouring and stirring, and at a certain point, no much more will dissolve, and the crystals will loss to the bottom the the glass. At this point, the equipment is said to it is in saturated. But hold ~ above – you can get an ext sugar crystals come dissolve by heater the water. Once you"ve got to the saturation point, and an ext sugar dissolves, you acquire a supersaturated solution. You can do this v salt, sugar, sodium acetate crystals and anything rather that will dissolve in water. In fact, you don"t even need water to produce a supersaturated solution. You deserve to do it through alcohol, paint thinner or any type of other solvent. It"s simplest to execute it with water, though, since water is the best solvent in the world.

You are watching: Describe how you would prepare a supersaturated solution.


Water is just one of the most interesting and also important chemical compounds over there is. Every water molecule is written of two positively charged hydrogen atoms and a negatively fee oxygen atom. The hydrogen atom arrange us on the much bigger oxygen atom to produce a network polarity native one next of the molecule come the other. Due to the fact that of this, water molecules kind bonds v each various other in a process called hydrogen bonding.


When you present a solute, such together sugar or salt, the water molecules are attracted come the solute atoms and also molecules much more strongly 보다 they are attracted to each other. Castle surround the solute molecules, and also as they do, the solute gradually disintegrates. Its component atoms and also molecules drift away, every one surrounded by water molecules, and also the solute dissolves. If you store stirring in an ext solute, though, you at some point run the end of water molecules to carry out this work, and at this point, the solution is saturated.


The way to do a supersaturated equipment is to add heat, but just a little heat won"t execute the job. You need to heat the water close come the cook point. As soon as the water gets this hot, the water molecules have much more freedom to relocate around, and also there is much more space because that solute molecules between them. You can keep stirring in salt, street or any other solute, and also it will proceed to dissolve, also though the saturation allude has to be reached. Take away the heat and also let the solution slowly cool, and the solute will continue to be dissolved, at least for a time. This is, in essence, the supersaturated definition. A supersaturated systems is highly unstable, and also strange things can happen.


Have you ever heard of hot ice? It"s produced from a supersaturated equipment of water and also sodium acetate crystals. Once you present a single sodium acetate crystal into such a solution, it"s choose a trigger that initiates a suddenly reaction through which all the excess sodium acetate in solution easily crystallizes. This is one exothermic procedure that gives off heat, therefore while the reaction produce ice-like crystals, it likewise produces heat, for this reason the name hot ice. To check out a dramatic show of crystal formation, pour the supersaturated solution slowly onto a couple of undissolved crystals. The crystallization wake up so conveniently that a decision tower will form as you pour.


A similar procedure occurs once you warmth water to the boil point, stir in sugar, let the solution cool and suspend a cable in the solution. The sugar slowly coalesces top top the string and forms a big crystal the you can enjoy together candy. A word come the wise: gain rock liquid in moderation, and be sure to brush your teeth. Sugar contributes come the formation of cavities.
