Concept explainers
Interpretation: The aqueous solution that has the lowest freezing point among the given solutions is to be stated.
Concept introduction: The addition of substance (solute) in a solvent is known as dissolution. After the process of dissolution the boiling point of solvent increases and the freezing point decreases. This decrease in freezing point is expressed as depression in freezing point. This depends upon the ionic and molecular property of the solute. Ionic compound after dissolution produces ions. The number of produced ions affects the value of depression in freezing point.
To determine: The aqueous solution that has the lowest freezing point among the given solutions.
