Yes, since the solubility of a solid solute in liquid solvent is decreased when the temperature is reduced, then the amount of of solute beyond the solubility limit must crystallize out of solution

Yes,since the solubility of solid will decreased by the decreasing of the temperature, so some of the potassium nitrates solid can't be dissolved anymore. So we can observe a phenomenon that some potassium nitrate get back to their original state: solid.

When does crystal happens?

When a saturated solution contains a nucleating point.


What happens when a crystal of salt is dropped into an unsaturated solution of the same salt?

Yes, because the solution is not yet saturated -- there is room for more solute to dissolve.


What happens when a solution of chlorine is mixed separately with potassium bromine solution and potassium iodide?

It is left as a low hazard


What happens when the temperature of a saturated copper sulphate solution is increased?

The solution will become unsaturated as the saturated concentration will increase. Solubility increases with temperature.


What happens when a crystal of solute is added to a unsaturated solution?

It will dissolve

A sodium chloride solution is obtained.


What happens when saturated solution of sodium chloride is electrolysed?

The products are sodium hydroxide and hydrogen.


Is there a reaction between ammonium chloride and potassium hydroxide?

No.If you add ammonium chloride solution to potassium chloride solution all that happens is a solution with all the ions in it - ammonium ions, potassium ions, chloride ions and hydroxide ions.


What happens when a solution of potassium iodide is added to a solution of lead nitrate taken in a test tube?

Lead iodide (Pb2I) precipitates as a yellow solid, leaving a solution of potassium and nitrate ions.


What happens when you add more solute to a saturated solution?

The solute normally doesn't dissolve and sinks to the bottom of the container. However, some saturated solutions can become super-saturated for a given temperature and pressure, by altering the conditions without allowing solute to precipitate.


What happens when iodine crystals are placed in water?

They will dissolve until the water is saturated then the remaining crystal will stay intact.
