Q: Answer-When a detergent is added to pure water, its surface tension –

When Soaps and detergents are added to water, they weaken the strength of the skin on the waters surface due to surface tension by interfering with hydrogen bonding between water molecules. It happens because the polar end of the soap or detergent is also attracted to the water, thereby decreasing the surface tension.
