What would happen to the crystallization temperature if you boil the solution?

Temperature of a solution is a condition that controls the solubility of solute in a solvent. Take copper sulfate for example. At 100° Celsius (C) 203.3 grams (g) can be dissolved in 100ml of water; at 0° C, only 31.6g can be dissolved in water.
If you continue to boil the solvent (water) away, the copper sulfate will come out of solution because the amount of water is lessened creating a supersaturated state that forces the solute out of the solution (in other words, the lesser amount of liquid water can't hold that much copper sulfate in solution.) Removing the heat source and allowing the solution to cool has the same effect. As it cools,the copper sulfate will come out of solution.
So, basically, concentration of the solute at a given temperature is the controlling factor. Boiling off the solvent increases the concentration; cooling the solvent decreases the concentration the solvent can hold. Both ways create a state of supersaturation leading to crystallization at all the temperatures in the given range.

If a seed crystal was added to a supersaturated solution how would you characterize the resulting solution?
If a seed crystal was added to a supersaturated solution, the resulting solution would be a crystallized solution. The formation of solid crystals that precipitate from a solution is called crystallization.
When you mixed room temperature salt and room temperature water the mixture changes temperature. If you leave this mixture undisturbed for several hours what would happen to the temperature?
The temperature of the water/salt solution will equalize to room temperature.
How is recrystallization temperature related to the grain size?
Grain size would generally increase during recrystallization with time spent at optimal crystallization temperature.
What would happen if you were to take a saturated solution at a certain temperature and cool it slowly?
the concentration of this solution is going to reduce.< Lets assume that the solution is comprised of water and salt> Then the water at a certain temperature begins to evaporate unlike the salt. at the end of the process, yes we agree that the solution has finally come to a room temperature, but concentration was lost during cooling. I mean that the solution becomes less concentrated
What would happen when sodium hydroxide is placed in salt water?
Nothing; other than; adding Solid NaOH or diluting a solution of NaOH with NaCl solution, will produce energy, resulting in a temperature increase.
What would increase the solubility of the solution?
increasing the temperature or pressure
Describe how you would make 1.0L of a supersaturated solution of CdI2?
I would take 351 g of CdI2 and heat it in hot water, have a soluable solution at that temperature, then decrease the temperature to have a supersaturated solution
What separation technique would you use for salt particles?
Crystallization (if there is a liquid as well, you would use evaporation and crystallization) :)
What would happen to a cell if it were placed into a solution of lower osmolarity?
it would burst
What would happen to gas if the temperature increases?
It would turn into liquid.
What will happen if a solution of sodium hydrogen carbonate heated?
Sodium carbonate would be deposited at the bottom of the solution.
What happens if you continue to add solute to saturated solution?
All that would happen is the solute would not absorb into the solution and it would spill off eventually.
