If we add salt to pure water boiling point will

Answer 1

Hey Friend,

If we add salt to pure water its boiling point increases.

Explanation - 
Not only salt, but any solute added to pure water leads to the alternation in the bonding of Hydrogen in H2O. When NaCl is added to water, it dissociates into Na+ and Cl- ions. These ions align themselves with the H2O bonding thereby increasing the inter-molecular attraction. 
Now, more energy is needed to break these bondings an therefore, there is a rise in the boiling point of the water. 

Note : Any impurities added to a pure solvent will lead to a rise in the boiling point of that solvent.

Hope it helps!
