Does water or isopropyl alcohol have a higher surface tension? Isopropyl alcohol has greater antibacterial capabilities than ethyl alcohol due to its greater depression of surface tension, and is therefore more toxic than ethyl alcohol. This reduces the surface tension, and the water does not hold its round shape and thus spills. Because they dont form hydrogen bonds, the clips sink through the surface. Isopropyl alcohol or isopropanol is a nonpolar solvent most commonly found at 50%, 70%, or 91% concentration, the remainder is purified water; this is a pharmaceutical grade of high purity. Note: Even though there are many ways to compare the surface tension of water and alcohol, the procedure written below compares each liquid on the surface of a penny. Water has a high surface tension because it is strongly attracted to itself. When a capillary tube is immersed in ethyl alcohol whose surface tension is 20 dyne `cm^(-1)`, the liquid rises to a height of 10 cm.
