Question

Big crystals are formed when a hot saturated solution is cooled slowly

1️⃣In a solution, a solvent (water) can only hold a certain amount of solute.

2️⃣This is called the solubility of a solution.

3️⃣When the temperature of the solution is increased, hot water can dissolve more solid substance than cold water.

4️⃣This is because heated water molecules move farther apart, making room for more solid substance to dissolve.

5️⃣When no more of the solid substance can be dissolved, the solution is said to be saturated.

6️⃣As this solution cools, the water molecules move closer together again and there's less room for the solution to hold onto as much of the dissolved solid.

Answer 2

Answer:

When we cool down a saturated solution.

The solute molecules break the bonding with the solvent molecules and all the solute molecules get seperated.And as a final result big solid crystals are formed.
