Question

 Out of 0.1 molal aqueous solution of glucose and 0.1 molal aqueous solution of KCl, which one will have higher boiling point and why? 

Answer 1

0.1 Molal aqueous solutions of KCl will have higher boiling point because it is an electrolyte solute and on addition to the solvent it will give 2 ions and thus the no.of moles increases and boiling point elevation will be more. 

`KCl → K^⊕ + Cl^-`
C6H12O6 → X (no dissociation)
