A supersaturated solution is a solution that contains more than the maximum amount of solute that is capable of being dissolved at a given temperature . The recrystallization of the excess dissolved solute in a supersaturated solution can be initiated by the addition of a tiny crystal of solute, called a seed crystal.
Which is the best description of a supersaturated solution quizlet?
supersaturated solution – a solution that contains more than the expected maximum possible amount of solute .
Which of the following best describes the term supersaturated?
“Supersaturated” describes a solution with a solute concentration greater than its solubility value .
Which of the following is a supersaturated solution?
A supersaturated solution is a more solute solution than can be dissolved by the solvent . If you haven't learned what a solute / solvent is, the material that is dissolved in the solution, such as salts but not restricted to salts, is a solution. The most popular example is sodium acetate which is supersaturated.
What characterizes a supersaturated solution?
If the solution is then carefully cooled back to its initial temperature, the excess solute will remain dissolved . The resultant solution is supersaturated, as it contains more than the maximum amount of solute that should dissolve in the given quantity of solvent.
How would you prepare a supersaturated solution?
Supersaturated solutions are generally prepared by dissolving your compound in heated water . If you add sugar, for example, to water at 25 degrees Celsius, about 210 grams of sugar will dissolve per 100 mL of water.
What happens when a supersaturated solution cools down quizlet?
What happens when a supersaturated solution cools down? The solute will precipitate out of the solution.
What do you mean by supersaturated solution?
A supersaturated solution is one which contains more dissolved solute than is needed to form a saturated solution at the same temperature ; From: Newnes Engineering and Physical Science Pocket Book, 1993.
What term best describes any solution?
Which of the following terms best describes any solution? ... homogeneous . You just studied 5 terms!
What does a supersaturated solution look like?
Remember, a supersaturated solution will look just like an unsaturated solution with no solute settled at the bottom . However, there is more solute than the solvent can actually hold. Any slight change to the solution will cause all of the solute to come out.
How do you know if a solution is supersaturated?
It's easy to tell if a solution is unsaturated, saturated, or supersaturated by adding a very small amount of solute . If the solution is unsaturated, the solute will dissolve. If the solution is saturated, it won't. If the solution is supersaturated, crystals will very quickly form around the solute you've added.
What can happen to a supersaturated solution?
Because that supersaturated solution holds more solute than is stable at the lower temperature, crystals start to form . As a result, some of the solute comes out of solution when crystals form. ... Crystal formation can only occur when you have an unstable supersaturated solution.
What happens when you agitate a supersaturated solution?
Supersaturated solutions are extremely unstable and will precipitate, or crystallize , upon addition of just one crystal of the sol- ute. Even slight shaking or agitation may be enough to cause crystallization to begin.
What is the difference between saturated solution and supersaturated solution?
Saturated Solution is a solution with solute that dissolves until it is unable to dissolve anymore, leaving the undissolved substances at the bottom, whereas, Supersaturated Solution is a solution (with more solute than the saturated solution) that contains more undissolved solute than the saturated solution because of ...
What is saturated solution give example?
A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved . At 20°C, the maximum amount of NaCl that will dissolve in 100. g of water is 36.0 g. ... When 40.0 g is added, 36.0 g dissolves and 4.0 g remains undissolved, forming a saturated solution.
Why is it challenging to prepare a supersaturated solution?
Explanation: because: super saturation is a highly exothermic reaction. a super saturated solution is very unstable .
