Question

Why elevation in boiling point take place when a non-volatile solute is added to a volatile solvent? explain

Answer 1

Answer:

∆Tb= Kb×m= Kb×(Wb/Mb)×1000/Wa

Explanation:

if non volatile solute is added no.of moles increases as molality increases.

so elevation in boiling point also increases.

imaginary-- when solute particles is added in volatile liquid then solute particles bind with liquid particles and to break this bond more heat is required so temperature increases as elevation in boiling point increases.
