How does soap affect hydrogen bonds between water molecules?

Soap is a surfactant, or a compound that lowers the surface tension of a liquid. Soap, in particular, decreases the surface tension of water by weakening the hydrogen bonds that make water such a special substance. This lower surface tension has two direct effects when it comes to the paper ball.

Similarly, what happens when soap is added to water?

Adding soap lowers the water's surface tension so the drop becomes weaker and breaks apart sooner. Making water molecules stick together less is what helps soaps clean dishes and clothes more easily.

Also, why does soap decrease the surface tension of water? Soap molecules are composed of long chains of carbon and hydrogen atoms. Since the surface tension forces become smaller as the distance between water molecules increases, the intervening soap molecules decrease the surface tension.

Considering this, how does the detergent affect the water?

Detergent and Soap Break Surface Tension The end of the detergent molecule which attaches to fat (grease) repels water molecules. It is known as hydrophobic, meaning "water fearing." By attempting to move away from the water molecules, the hydrophobic ends of the detergent molecules push up to the surface.

How does hydrogen bonds affect the surface tension of water?

When many water molecules form hydrogen bonds with other water molecules, they form a lattice of water molecules, which is strong and flexible. This creates a high surface tension. As a result, this molecule at the surface tends to be pulled into the bulk of the liquid and thus minimizes the surface area of a liquid.
