1. Various salts, when added to the sodium taurocholate solution, lower the surface tension of the latter differently according to their nature.
2. The influence of the salt in higher concentration can be interpreted as the result of hydration of the salts, while the effect at much lower concentration is related to the nature of cations.
3. Cations which form a less dissociable taurocholate salt are found more effective in lowering the surface tension of sodium taurocholate solution.
4. Surface tension of taurocholic acid and its salt is caused by the accumulation of them as molecules on the surface of solution.
5. The solutions of sodium, calcium and copper taurocholate show a minimum surface tension of their own, differing from each other. This indicates the fact that the surface activity of the surface film of various tauroeholates have different values.
