An aqueous solution of 10% (consider ideal behaviour of the solution) is cooled. It will allow some — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

When an aqueous solution containing a non-volatile solute like $NaCl$ is cooled below its freezing point, only the pure solvent (water) begins to freeze out and separate as ice. The solute ($NaCl$) remains dissolved in the liquid phase, making the remaining solution more concentrated.
