Question

The normal temperature range of the liquid phase of pure water is 0 degrees Celsius to 100 degrees Celsius. Which of the following aqueous solutions has the largest liquid phase range?

a. 0.1M C2H5OH
b. 0.1 M KBr
c. 0.2 M MgBr2
d. 0.2 M MgSO4

Answer 1

a. 0.1M C2H5OH

Step-by-step explanation:

This could be considered using the idea of colligative property of solutions.

Colligative properties are those properties of solutions that depend on the ratio of the number of solute particles to the number of solvent molecules in a solution, and not on the nature of the chemical species present. The number ratio can be related to the various units for concentration of solutions.
