Water has a high surface tension because of the strong hydrogen bonds between its molecules. There is a common misconception that water does not have the necessary surface tension to maintain a bubble and that soap increases it, but in fact soap decreases the pull of surface tension typically to about a third that of plain water. Why does soap decrease the surface tension of of water It keeps water molecules away from the surface. Greater electronegativity of the hydrogen bond acceptor will lead to an increase in hydrogen-bond strength.
