You can prepare what is called a supersaturated solution. This is a solution that has more solute in it than "should" dissolve at a particular temperature.
- Make sure you have a clean and preferably new, unscratched container. Try not to add microscopic scratches to the container when stirring. A new unused glass beaker is ideal and stir with a plastic spatula.
- Prepare a saturated solution ie dissolve as much solute as you can into the liquid at a particular temperature.
- Heat the solution to a higher temperature. Your choice but 10 - 20 ºC is fine.
- Now carefully add more solute and stir. You do not want any solute particles sitting on the base so if you have some, either heat a little more or add a little more liquid.
- Cover, you do not want dust particles.
- Allow to cool slowly.
- You have a supersaturated solution that contains more solid solute than can be dissolved into the liquid. Congratulations.
What can go wrong:
It crystallises before it cools very much. Solution: do not be so ambitious with the change of temperature. It was too great a load for the solution to carry.
One really cool thing to do next is to tap the side of the container, or to scratch the bottom of the beaker with a glass rod, or to drop a single tiny crystal into your supersaturated solution. Bingo, it will instantly drop the extra solute. Why? You provided it with nucleation sites for the crystals to form. It takes a little activation energy for crystals to form, you have to be careful not to provide it when the solution is being prepared. Just a scratch or even a knock will provide the nucleation site or the energy.

Will all solids desolve on water?
No, lead is a solid that won't dissolve in water, though solid ice will.
Do all SOLID partcles dissolved in WATER. why?
No. Only solid stuff with special chemicals in them dissolve, like sugar and salt. Notice that things only dissolve in warm water, and never ice water. Example: If you put sand in water, it doesn't dissolve.
What happens if solids are soluble in water?
They will dissolve in the water and form a solution. The amount that will dissolve depends on the solubility of the solid and the temperature.
