Surface tension is the property of liquid by which it tries to minimize its free surface area.
If impurity is mixed in liquid, the surface tension of liquid decreases.
The soluble substances when dissolved in water, decreases the surface tension.
For example : Insects and mosquitoes swim on the surface of water in ponds and lakes.
If impurity like kerosene is added, the surface tension of water is lowered and insects and mosquitoes sink in water and die.

As surface tension increases, intermolecular forces increase. ... The Presence of ImpuritiesThe presence ofimpurities on the surface of, or dissolved in, a substance directly affects the surface tension of theliquid. The surface tension of water, for example, will increase when highly soluble impurities are added to it.Sep 23, 2013
