Question

0.50 mole of KCI, a strong electrolyte, is added to 2.0kg of water. The boiling point of the solution will be _____ the boiling point of pure water.
- higher then
- lower then
- the same as

Please explain!

Answer 1

Answer:

Higher than

Explanation:

The boiling point of a solution is a colligative property

Atoms present ∝ Colligative Property (Boiling Point)

Since KCl is a strong electrolyte, it completely dissociates into K⁺ and Cl⁻ ions, which doubles the number of atoms as compared to what was initially added

Now it's competition is very weak, Pure water has nothing else dissolved in it. which means that our solution will have much higher boiling point as compared to Pure Water
