✦ Synopsis

The surface tension of the aqueous solutions of sodium halides (NaF, NaBr, and NaI), sodium salts with polyatomic anions (Na 2 CO 3 and Na 2 SO 4 ), mixtures (NaCl + NaI and NaCl + Na 2 SO 4 ), and seawater have been determined using a drop volume method, in a concentration range of 0 to about 1 mol kg -1 and at temperatures ranging from 15 • to 35 • C. The surface tension data have been analyzed in view of K. Motomura's thermodynamic treatment (J. Colloid Interface Sci., 64, 348 (1978)), and the thermodynamic quantities relevant to surface have been shown systematically.
