Question

A group of students is in the laboratory performing an experiment on the effect of adding salt to water. Which observation are students likely to make as they increase the molality of the saltwater solution?

Answer 1

Increasing the molality of a saltwater solution leads to several observable changes in the solution.

Step-by-step explanation:

When salt is added to water, the molality of the saltwater solution increases. As the molality of the solution increases, several observations are likely to be made:

1. The boiling point of the solution increases.
2. The freezing point of the solution decreases.
3. The osmolarity of the solution increases.
4. The conductivity of the solution increases.

These observations occur because salt dissociates into ions in water, which affects the physical properties of the solution.
