Soapy water does have some surface tension to it but it is very negligible. However pure water have good surface tension due to strong hydrogen bonding. This is the reason a water strider bug can walk and paperclip will float on water.

Which has more surface tension clean water or soapy water?
Yes, pure water is a one molecule based structure, which hold together better than a mixture. When soap or other chemical is added, it breaks surface tension by getting in the way of each water molecule. Try putting water drops on a penny to build a bubble, then add a small drop of soap to it, you'll see that when soap is added, the water bubble collapses.
What is a force that acts on particles at a liquids surface?
Surface tension. It always tends to acquire minimum surface area thats why water droplets form spherical shape.
How would you separate a mixture of wood and gold?
use soapy water. the wood will float the gold will sink. the soap reduces the surface tension, preventing tiny particles of gold from floating.
How does soap effects the surface tension if water?
the surface tension has bonds, and the soap breaks those bonds, so if the soap water is put onto a surface.. it will slip off
Why does soap reduce the surface tension of water?
Soap will lower the surface tension of water. Like any surfactant soap will lower the surface energy by disrupting the strong inter-molecular hydrogen bonding that confers such a strong surface tension to water.
Why does tap water have greater surface tension than soapy water?
Because honey is stikier
Can a needle float in soapy water?
Yes it is not possible. Because as soap is added then surface tension would get reduced and so possibility of float becomes less. When we carefully place the same needle on ordinary water floating is quite possible as water has more surface tension

What is the effect of sodium chloride on the surface tension of water?
The surface tension of water is increased for salted water.Sodium chloride increase the surface tension of water.
Why does a blade sink on soapy water?
You can float a razor blade on water due to the 'Surface Tension' of the water. This is the tendancy of the water molecules to stay tightly together, which is why a water drop forms a 'hump' on a surface. Soap is a 'wetting agent', or surfactant. When you add soap to the liquid, the surface tension is drastically reduced, and the water molecules 'flow' around objects, like the razor blade. So, it sinks.
What makes a needle to float in water?
Water surface tension hold the needle on the water surface.
What property of water let's bugs walk on water?
surface tension
A consequence of the surface tension of water is?
The surface tension of water is responsible for the cohesive properties it exhibits. For example, capillary action is a consequence of surface tension.
How does surface tension of water compare with the surface tension of most other liquid?
The surface tension of water is higher than that of most other liquids. Water has a surface tension of 7.29 * 10-2 J/m2 at 20oC.
Does water have a relatively high or low surface tension?
MERCURY has a higher surface tension than water. This highest surface tension between liquids is 487 mN/m at 15 0C.
Does water have the highest surface tension?
No, mercury has a higher surface tension.
What is a force that acts on particles at a liquids surface?
Surface tension. It always tends to acquire minimum surface area thats why water droplets form spherical shape.
