What will happen if a saturated solution of copper chloride is cooled?

A cooled saturated solution of copper chloride will precipitate crystals of copper chloride.


How will you obtain pure copper sulphate crystal?

boil off the solvent (usually water) until you are left with copper sulfate crystals. For getting back the copper sulphate crystals from copper sulphate solution, we have to first make super saturated solution by boiling, then allow to cool down & dried these crystals with filter paper.


When a saturated solution is cooled some crystals begin to appear in the solution is the solution now unsaturated?

No, the solution remains saturated. It is just that as the temperatures decreases so does the carrying capacity of the solvent.


What evidence do you have that the equilibrium shifted when saturated potassium nitrate solution was cooled?

The solution forms bigger crystals that have pointed ends.


Why crystals start to form as saturated solution is being cooled?

On cooling saturated solutions, the excess solute precipitates as a solid. This can take the form of a powder or a crystal structure.


What is crystallisation of salts?

When there is no more solute can be dissolved in a solution, a saturated solution is obtained. When a hot saturation solution is cooled down the solute will come out in solid form as a crystal. Small crystals will be found in fast cooling. If we hang a small crystal in a h ot saturated solution it will grow bigger when it cools slowly.

What would happen if a hot saturated solution was cooled slowly?

Crystallisation


When a hot saturated solution is cooled?

The solute will gradually form a precipitate.


What would happen if a hot saturated solution was cooled quickly?

There Is No Way A Saturated Solution Can Be Cooled Quickly. But If It Did The Solution Would Desaturate.


What causes the equilibrium to shift when a cooled saturated potassium nitrate solution is added to water?

When a cooled saturated potassium nitrate solution is added to water, the concentration of the potassium nitrate decreases making it less likely that he substance will precipitate out of solution.


What term describes a solution that contains the maximum amount of soluteit can hold?

A solution that has the maximum amount of solute dissolved at that temperature is known as a saturated solution.However it is possible to prepare a super saturated solution by heating the solution slightly, dissolving the maximum amount of solute and then carefully cooling the solution. Generally the super saturated solution is unstable and the excess solute will precipitate out if given the energy to do so.A common super saturated solution is a sugar solution. Sugar is added to water and the solution is heated and then carefully cooled. The solution can form a glass like solid called "toffee" rather than crystals of sugar.


What heppen when hot saturated solution is cooled?

Either it becomes "supersaturated" OR some material separates out (precipitates).
