Which of the following aqueous solution will have the highest boiling point

a. 0. 20 m glucose
b. 0.25 m sucrose
c. 0.10 m na2so4
d. 0.10 m nacl

also give reasons

Ionic molecules have higher boiling point than covalent molecules.

So that leaves Na2SO4 and NaCl.

The ionic molecule with higher charge will have higher boiling point.

Na2SO4 have ions with charge +-2.

NaCl have ions with charge +-1.

So the answer is C.

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

they are all solids.
