Which of the following liquids is likely to have the highest surface tension?
Since hydrogen bonding is stronger than dipole-dipole forces and London dispersion forces, molecules held by hydrogen bonding will be more attracted to each other. This results in high surface tension. Therefore, CH3OH C H 3 O H has the highest surface tension among the four covalent compounds.
Does water have a higher surface tension than soapy water?
You should find that plain tap water produces a much larger, stable drop of water on top of the penny than the soapy water does. This is because plain tap water has higher surface tension, so the surface is “stronger” and can hold together a larger drop.
Why does sugar increase the surface tension of water?
Why does glucose increase surface tension? In a dispersed system, sugars are repelled by the hydrophobic surface, thus living a thin zone inside the hydrophilic/hydrophobic interface that is depleted of sugar molecules, giving rise to a higher apparent surface tension (Docoslis, Giese, & van Oss, 2000) .
Does salt water have more surface tension than water?
Does salt water have higher surface tension? Yes, adding salt to water does increase the surface tension of water, although not by any significant amount. However, experiments done with salt water show that surface tension actually increases when salt is added to pure water.
Why h2o has higher boiling point?
Water has an unusually high boiling point for a liquid. … Water is made up of oxygen and hydrogen and can form hydrogen bonds, which are particularly strong intermolecular forces. These strong intermolecular forces cause the water molecules to “stick” to one another and resist transition to the gaseous phase.
