describe the relationship between surface tension and intermolecular forces of attraction found among the pure water sample versus the water-detergent mixture

Question

 hydrogen bonding in water lab

Answer 1

Actually, detergents cause the surface tension of water to decrease.

 

Surface tension of water is caused by an intermolecular force called hydrogen bonding.

 

The detergent interferes with the hydrogen bonding occurring between the water molecules thereby decreasing the surface tension.
