Question

when salt s added to water what happens to its boiling and melting pint

Answer 1

Presence of any imputity say common salt, in a solvent like water causes “Elevation in Boiling point” and “Depression in Freezing point” of that solvent. So the boiling point of water will increase.

When salt is added to water, then the intermolecular forces between water molecules gets altered due to dissociation of NaCl into sodium and chloride ions. The hydrogen bonding( a weak bond) between water molecules gets affected and the ion-dipole interaction between ions (sodium and chloride ions) and dipole (water) starts occuring. Ion-dipole interaction is comparatively strong bond. Hence more heat is required by water molecules to come out as gaseous phase and vaporise.
