One mole of sodium chloride is added to 100 mL of water in beaker A.One mole of glucose,C₆H₁₂O_6, is added to 100 mL of water in beaker B.How much more will the freezing point of water be lowered in beaker A than in beaker B?

Question

Quizplus · Accepted Answer

Sodium chloride (NaCl) dissociates into two ions (Na+ and Cl-) when dissolved in water, effectively doubling the number of particles in solution compared to glucose, which does not dissociate. The freezing point depression is directly proportional to the molal concentration of particles in solution. Therefore, the freezing point of water in beaker A will be lowered twice as much as in beaker B.
