Assuming ideal behavior, the change in the freezing point (∆Tf) for a 0.171 m solution of NaCl in an unknown polar solvent is found to be -6.81℃. Again, assuming ideal behavior, the change in the freezing point for a 0.684 m solution of NaCl in the same polar solvent will be ________.

 

 

a.)-27.24℃
b.)-6.81℃
c.)+6.81℃
d.)-54.48℃
e.)-13.62 ℃
Expert Solution
Step 1

The question is based on the concept of solutions.

depression in freezing point is a colligative property. on making solution, freezing point of solvent is depressed.

This is because more amount of energy required to freeze the solution due to unlike interaction between solute and solvent.
