Which of the following solutions will exhibit highest boiling point?

Step-by-step solution

For, assume complete dissociation For Na ₂ SO ₄ ; i=3, m=0.01 aligned & T_ b =i K_ b m & T_ b =3 K_ b 0.01=0.03 K_ b aligned For, 0.01 M KNO ₃ ; aligned i &=2, m=0.01 T_ b &=2 K_ b 0.01 K_ b =0.02 K_ b aligned While, urea and glucose are non-electrolyte They do not dissociate into ions highest boiling point is shown by 0.01 M Na ₂ SO ₄(a q) solution.
