Solubility controls the formation of crystals by the mechanism of oversaturation, therefore the correct answer is:
4. The water polo would need to be heated to a higher temperature, which would give molecules and ions more kinetic energy, increasing solubility.
Crystals are solid structures where there is a fixed spatial arrangement of the molecules, there are many preparation methods, a very practical method and obtaining good crystals is from supersaturated solutions.
Solubility is the mechanism by which a supersaturated solution is formed, for this it is used that the water when heated has more energy and manages to dissolve a greater amount of solute, therefore by decreasing the temperature and consequently reducing the solubility the solution is over saturated.
When introducing some means of disturbance in the solution, the excess of solute is deposited in the form of crystals of excellent quality, this growth method is called hydrothermal synthesis
To achieve controlled supersaturation and crystals the temperature must be controlled precisely, to allow the formation of the crystals.
In conclusion, solubility controls the formation of crystals by the mechanism of over saturation, therefore the correct answer is:
4. The water polo would need to be heated to a higher temperature, which would give molecules and ions more kinetic energy, increasing solubility.
