High surface tension causes water to behave as if its surface had an elastic membrane, which was stretched. Due to water's high surface tension, effects like tears of wine and rain water beading on a leaf or grass happen.
Between water molecules a big cohesion force exist; this is the cause of the high surface tension of water.
MERCURY has a higher surface tension than water. This highest surface tension between liquids is 487 mN/m at 15 0C.
The pH of water is not related to surface tension.

The reason behind the high surface tension of water is hydrogen bonds. This very strong bond enables small insects to walk on the surface of water.
Water has a relatively high surface tension compared to other liquids, due to hydrogen bonding.

Hydrogen bonding causes the inward force that minimizes the surface area of water, and the tendency of water molecules escaping this bond to become vapor is slim and/or slow, thus creating it's low pressure.
The oil is not repelled. It is floating on the surface of the water as a thin film. Water has very high surface tension, but when soap or detergent is added to water that surface tension suddenly drops. The water surface now contracts like a punctured rubber sheet toward the remaining area of high surface tension, dragging the oil film floating on its surface with it.
A high surface tension
Certain insects (ones with a very light weight) are able to walk on water as their weight does not break the surface tension of the water. Water has a very high surface tension, therefore easily breaking and not supporting weight above a certain limit.
Water molecules are linked by a high cohesive force.
