Crystallization of Copper Sulphate (CuSO4) | Experiment | Practical Class 9th and 11th |

Описание: CuSO4 Crystallization

The principle behind the crystallization of CuSO4 (copper sulfate) is based on the concept of supersaturation.

When a solid compound, such as CuSO4, is dissolved in a solvent, such as water, it forms a solution. As more of the compound is added to the solvent, it dissolves until a point is reached where no more solid can be dissolved in the liquid at that temperature. This point is known as the saturation point.

If the solution is then allowed to cool slowly, the solubility of the compound decreases with decreasing temperature. This creates a condition of supersaturation, where the solution contains more dissolved solid than it would normally be able to hold at that temperature.

Under supersaturated conditions, the excess dissolved solid starts to come out of the solution and form crystals. This process is known as crystallization.

In the case of CuSO4, when a saturated solution of copper sulfate is cooled, the CuSO4 molecules come together and arrange themselves in a highly ordered, repeating pattern, forming crystals of CuSO4. These crystals can be further purified and harvested by filtration or other separation techniques.
