A hot saturated solution of copper sulphate forms crystals as it cools. Why? |
| Answer» Solution :The capability of a solution to maintain a CERTAIN CONCENTRATION of solute is temperature dependent. When a saturated solution of copper sulphate at above room temperature is allowed to cool, the solution BECOMES super-saturated and in the absence of stirring or the return of the previous solution temperature, the solute STARTS to precipitate out. i.e., crystal formation occurs. | |
