Abstract: The behaviour of water in H2O-CHCl3-CCl4 system is studied.by 1H NMR method.Water is thought to exist in the form of H2O, H2O·CHCl3, (H2O)2 and (H2O)2·CHCl3 in the system .The formation constants for the species of H2O·CHCl3, (H2O)2 and (H2O)2·CHCl3 evaluated from NMR data are 1.56, 15.3 and 18.5 (mole fraction) respectively.

Key words: Water, Chloroform, Hydrogen bond, Association, NMR
