Question

What would you observe when

(a) a saturated solution of potassium chloride prepared at $60°\mathrm{C}$ is allowed to cool to room temperature.

Answer 1

Chemical reaction:

• “The process in which change in the chemical composition of substances takes place is called a chemical reaction.”

Observations when a saturated solution of Potassium chloride is prepared at $60°\mathrm{C}$ :

• A saturated solution is that in which a maximum amount of solute is dissolved at a particular temperature.
• If a saturated solution of Potassium chloride is prepared at $60°\mathrm{C}$, then on cooling the solution to room temperature, solid Potassium chloride $\left(\mathrm{KCl}\right)$ is separated out from the saturated solution.
• The crystals of Potassium chloride will be formed.
