Question

Dissolving salt in water reduces the intermolecular forces between water molecules. What most likely happens to the surface tension of water when salt is dissolved in it?

Answer 1

the answer is b. it decreases

Answer 2

If we dissolve salt in water they will reduce the intermolecular forces between water molecule and this will decrease the surface tension.

Surface tension is due to cohesive forces (the forces between molecules of same substance) hence as cohesive forces decreases the surface tension also decreases
