Question

out of 0.1 molal solution of glucose and kcl which one will have a higher boiling point and why

Answer 1

In the same volume of water,0.1 mole of KCl will have a greater boiling point elevation as,boiling point elevation is a colligative property, which depends on the relative amounts of the constituents and not on their identity.

Since,more ions will be produced by KCl (ionic compound) than glucose(covalent compound) as there are more component parts in the KCl molecule, so the KCl solution will have more boiling point.

Hope it will help u...!

Answer 2

0.1 molal solution of KCl have a higher boiling point because KCl is an ionic compound.

  0.1 molar of KCl will have a high boiling point in the same volume of water, as we considered boiling point is a colligative property that depends on the relative amount of the constituents and it does not depend on the identity of the compound.

  Since KCl will produce more ions than glucose, KCl is an ionic compound where it is a covalent compound as glucose. Because the KCl molecules have more components, the KCl will have more boiling points.
