Question

Watee ae you avadsouthe concentration of some solute, X, is 2.0 water 9. Solubility depends on temperature Solution is saturated at 25 C when the g/mL, but the saturated solution at 50°C has Imagine Consider a situation where a a concentration of 5.0 g/mL grams of you were to cool the solution to tually ex of X to you have a expect on containing 5.0 g of X in 1 mL of solid X to "come out" of solution. This process is called crystallization or precipitation. remain in a Eventually, we ex no further changes will occur and is solution; at this point, the solution is saturated at 25oCj no further changes will be ex crystallization e have reached a stable or equilibrium state. The rate of not always happen time when no a occur; we say that we have reached a st now equal to its rate of dissolution. Equilibrium does changes are occurring; in these cases, we have what supersaturated. Thus, a supersaturated solution is in instantaneously; sometimes, there may be a perio pparent is called say that the solution is a metastable or quasi-equilibrium condition. In this particular case, we a metastable or an equilibrium) state, whereas a saturated solution s in(a metastable or an equilibrium) state. ere is not enough solute available to produce a saturated solution, then If th we say that it is unsaturated. At 25°C, the solubility of NaCl in water is 8/mL. At 100°C, it is 0.39 g/mL. If 0.36 g of Nal were mixed with 1 mL of water, the solution at 25°C will be or unsaturated). At 100°C, the solution will be supersaturated, or unsaturated). If 0.46 g of NaCl were mixed with water, the solution at 25°C will be 0.36 saturated, supersaturated, saturated, (saturated, supersaturated, or unsaturated). At 100°C, the solution will be (saturated, supersaturated, or unsaturated). 10. Submit a one-page summary of your research about the composition of the materials you used in Procedure 1. Be specific. If you say that something is made up of neutral atoms, specify what the atoms are. If you say that something is made up of ions, specific what the ions are. If you something is made up of molecules, specify what the molecules are. say

Explanation / Answer

Since at 25oC , saturated solution should contain only 2 grams per ml of solution. Therefore, 3 gm of the solute should come out when solution with 5 gm per ml is cooled from 50oC to 25oC.

Thus, the remaining X will be 5-3 = 2 grams. This particular case of supersaturated solution is quasi-equilibrium while saturated solution will be in equilibrium state.

For NaCl case :

At 25oC , it will be saturated solution .

At 100oC , it will be unsaturated solution.

With 0.46 gm/ml concentration :

At 25oC , solution will be supersaturated.

At 100oC, solution will be supersaturated
