ABSTRACT:
Interfacial tension between two liquids water and immiscible organic liquid lighter than water has been determined by capillary rise method. The difficulties encountered in the determination of interfacial tension by capillary rise method and how to overcome these difficulties has been discussed. The interfacial tensions between water and organic liquids benzene, toluene, p-xylene and n-hexane which are lighter than water have been determined at room temperature (30±1oC) using a pyrex glass capillary tube of uniform bore size. The values of the interfacial tension determined by the capillary rise method were in close agreement with the reported values by methods other than the capillary rise method.
