A saturated solution is a mixture in which the maximum amount of a given solute has been dissolved into the solvent. You know you have a saturated solution as it will generally contain some undissolved solid solute. A saturated solution is at equilibrium. What happens to the undissolved solute in a saturated solution when it is heated?If a saturated solution is heated, then it becomes unsaturated because solubility of solute increases on heating. When equilibrium between the dissolved and undissolved solute is reached the solution must be?When the solution equilibrium point is reached and no more solute will dissolve, the solution is said to be saturated. A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved. What contains undissolved solute in equilibrium with dissolved solute? saturated solution How can you describe the state of equilibrium in a saturated solution that contains undissolved? How can you describe the equilibrium in a saturated solution? In a saturated solution, a state of dynamic equilibrium exists between the solution and any undissolved solute, provided that the temp remains constant. How can you get the undissolved solute in a saturated solution to dissolve?We can prepare a homogeneous saturated solution by adding excess solute (in this case, greater than 35.9 g of NaCl) to the solvent (water), stirring until the maximum possible amount of solute has dissolved, and then removing undissolved solute by filtration. Can a solution with undissolved solute be supersaturated?A supersaturated solution cannot contain undissolved solute, as the presence of undissolved solute would indicate that the solution is a saturated… When a solution is saturated and additional solid solute is added what happens?If more solute is added and it does not dissolve, then the original solution was saturated. If the added solute dissolves, then the original solution was unsaturated. A solution that has been allowed to reach equilibrium but which has extra undissolved solute at the bottom of the container must be saturated. When equilibrium is established between dissolved and undissolved solute at a definite temperature solution is termed as? A saturated solution: It is one in which an equilibrium is established between dissolved and undissolved solute at a definite temperature. Which salt has the greatest change in solubility between 30ºc and 50ºc? KCl What describes a saturated solution and any undissolved solute?Saturated Solution. A solution containing the max amount of solute for a given amount of solvent at a constant temp and pressure; an equilibrium exists between undissolved solute and ions in solution. What is at equilibrium when undissolved solute is visible?There is a dynamic equilibrium between the dissolving and the re-crystalization of the solute. From this point on, undissolved solute particles wiil be visible in the solution. A solution becomes supersaturated if it contains more solute than it is capable of dissolving at a particular temperature and volume. When is a saturated solution is at equilibrium?A saturated solution is at equilibrium. The rate of dissolution and the rate of reforming the solid solute are equal. When the concentration is below the saturation concentration, then any solid will spontaneously dissolve. Once sufficient solute has dissolved and the system is at equilibrium, the net dissolution will stop. When does net dissolution of a saturated solution stop? Saturated Solutions. The rate of dissolution and the rate of reforming the solid solute are equal. When the concentration is below the saturation concentration, then any solid will spontaneously dissolve. Once sufficient solute has dissolved and the system is at equilibrium, the net dissolution will stop. How can you tell if a solution is saturated or unsaturated? How can you tell if a solution is saturated or unsaturated? If more solute is added and it does not dissolve, then the original solution was saturated. If the added solute dissolves, then the original solution was unsaturated. A solution that has been allowed to reach equilibrium but which has extra undissolved solute at the bottom Which is the maximum amount of solute in a saturated solution?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. RelatedWhen compounds are synthesized, contaminating materials are often mixed in with them. The process of recrystallization can be used to remove these impurities. The crystals are dissolved in a hot solvent, forming a solution. When the solvent is cooled, the compound is no longer as soluble and will precipitate out of solution, leaving contaminating materials still dissolved.
Table salt \(\left( \ce{NaCl} \right)\) readily dissolves in water. Suppose that you have a beaker of water to which you add some salt, stirring until it dissolves. You add more and that dissolves. You keep adding more and more salt, eventually reaching a point at which no more of the salt will dissolve—no matter how long or how vigorously you stir it. Why? On the molecular level, we know that action of the water causes the individual ions to break apart from the salt crystal and enter the solution, where they remain hydrated by water molecules. What also happens is that some of the dissolved ions collide back again with the crystal and remain there. Recrystallization is the process of dissolved solute returning to the solid state. At some point, the rate at which the solid salt is dissolving becomes equal to the rate at which the dissolved solute is recrystallizing. When that point is reached, the total amount of dissolved salt remains unchanged. Solution equilibrium is the physical state described by the opposing processes of dissolution and recrystallization occurring at the same rate. The solution equilibrium for the dissolution of sodium chloride can be represented by one of two equations: \[\ce{NaCl} \left( s \right) \rightleftharpoons \ce{NaCl} \left( aq \right)\nonumber \] While the above equation shows the change of state back and forth between solid and aqueous solution, the preferred equation also shows the dissociation that occurs as an ionic solid dissolves: \[\ce{NaCl} \left( s \right) \rightleftharpoons \ce{Na^+} \left( aq \right) + \ce{Cl^-} \left( aq \right)\nonumber \] When the solution equilibrium point is reached and no more solute will dissolve, the solution is said to be saturated. A saturated solution is a solution that contains the maximum amount of solute that is capable of dissolving. At \(20^\text{o} \text{C}\), the maximum amount of \(\ce{NaCl}\) that will dissolve in \100. \: \text{g}\) of water is \(36.0 \: \text{g}\). If any more \(\ce{NaCl}\) is added past this point, it will not dissolve, because the solution is saturated. What if more water is added to the solution instead? In that case, more \(\ce{NaCl}\) would be capable of dissolving in the additional solvent. An unsaturated solution is a solution that contains less than the maximum amount of solute that is capable of being dissolved. The figure below illustrates the above process and shows the distinction between unsaturated and saturated. How can you tell if a solution is saturated or unsaturated? If more solute is added and it does not dissolve, then the original solution was saturated. If the added solute dissolves, then the original solution was unsaturated. A solution that has been allowed to reach equilibrium, but which has extra undissolved solute at the bottom of the container, must be saturated. |
