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.
Clean water has nore surface tension than soapy water. The soap in the water sort of breaks up hydrogen bonds. This makes the water a more efficient cleaner because with less surface tension it will soak into clothes, etc. instead of bearing up.
Yes, the addition of surfactants such as soap lowers the surface tension of water.
Tap water!
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.
Surface tension. It always tends to acquire minimum surface area thats why water droplets form spherical shape.
use soapy water. the wood will float the gold will sink. the soap reduces the surface tension, preventing tiny particles of gold from floating.
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
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.

Because honey is stikier
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
The surface tension of water is increased for salted water.Sodium chloride increase the surface tension of 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.
Water surface tension hold the needle on the water surface.
surface tension
The surface tension of water is responsible for the cohesive properties it exhibits. For example, capillary action is a consequence of surface tension.
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.
MERCURY has a higher surface tension than water. This highest surface tension between liquids is 487 mN/m at 15 0C.
No, mercury has a higher surface tension.
