Question

arrange the solutions in order from highest freezing temperature to lowest freezing temperature. assume that each solution has a volume of 100 ml. highest freezing temperature water with 1/2 teaspoon of dissolved sugar water with 1 teaspoon of dissolved sugar pure water water with 2 teaspoons of dissolved sugar lowest freezing temperature

Explanation:

Step1: Recall colligative - property concept

The freezing - point depression is a colligative property. The more solute particles in a solution, the lower the freezing point.

Step2: Compare solute amounts

Pure water has no solute. 1/2 teaspoon of sugar has less solute than 1 teaspoon, and 1 teaspoon has less solute than 2 teaspoons.

Answer:

pure water, water with 1/2 teaspoon of dissolved sugar, water with 1 teaspoon of dissolved sugar, water with 2 teaspoons of dissolved sugar
