What is the effect of pH on surface tension?
For most liquids, an increase in pH results in decreased surface tension. This has been attributed to lower attraction force between molecules when pH rises.
Which will have the higher surface tension C6H6 or C3H7OH?
The surface tension of benzene is 28,89 dyn at 20 oC.The surface tension of 2-propanol is 21,70 dyn at 20 oC.
What will boil first water or alcohol?
I assume that by "boils faster" you really mean "boils at a lower temperature", and that by "alcohol" you mean "ethanol". Ethanol has a lower boiling temperature than water at standard pressure. However, a mixture of ethanol and water boils lower than either by themselves do. This is called an "azeotrope" and it happens for ethanol/water mixtures at about 95% ethanol, which is why it's essentially impossible to get ethanol to more than 190 proof by distillation alone.
Does cooking oil have more surface tension than water?
Because of the polarity of the water molecule, hydrogen bonds form between them. This results in the higher surface tension. Oil is nonpolar, so hydrogen bonds do not form between the molecules, so the surface tension is less.
Which is more soluble in water propane or ethanol?
Ethanol---it has stronger intermolecular forces due to its ability to hydgrogen bond (because it has an -OH group) that propane. Both of them have similar dispersion forces because they have around the same number of electrons, so the presence of hydrogen bonding in ethanol will give ethanol the greater intermolecular forces and hence the higher surface tension.

Does water have the highest surface tension?
No, mercury has a higher surface tension.
Which will have the higher surface tension C6H6 or C3H7OH?
The surface tension of benzene is 28,89 dyn at 20 oC.The surface tension of 2-propanol is 21,70 dyn at 20 oC.
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.
Why does water have higher surface tension than oil?
Because of the polarity of the water molecule, hydrogen bonds form between them. This results in the higher surface tension. Oil is nonpolar, so hydrogen bonds do not form between the molecules, so the surface tension is less.
Do small molecules have high surface tension?
Generally larger molecules with stronger intermolecular forces have higher surface tension. This tendency can be seen if you look at the surface tensions of the alkanes. Water is a clear exeption to this pattern due to the very strong hydrogen bonds.
How does the surface tension of water compare with the tensions of most other liquids?
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.
Why did heating the water affect the surface tension?
Surface tension is lower at higher temperatures.
What properties of water is much higher than predicted?
Surface tension, boiling point.
How does surface tension and viscosity affect the flow of liquids?
Viscosity is the resistance of flow and surface tension is the lateral force of the bonds between the molecules
Do liquids that have higher tension produce drops that are flatter or more nearly sperical ttan liquids with lowersurface tension?
Surface tension causes molecules to hold to themselves more tightly. Therefore high surface tension liquids, like pure water, will form a taller drop and low surface tension substances, like oil, will spread out and be flat.
