5-bromosalicylic, 5-sulphosalicylic and 3-nitrosalicylic acids increase the negative potential of the air/water boundary. The first compound is the most active; it changes the potential by 270 mV at a concentration of 0@03 M (pH 2.1) and decreases the surface tension to 70.2 dyn/cm. The increase of

Phenylarsonic acid changes the potential at the free surface of 0.1 M KC1 from -23 to -275 mV and the surface tension from 72.3 to 67.7 dy/cm over the concentration range from 0.01 to 0.1 M. o-and p-methyl derivatives of this acid are far more active; they decrease the potential to about -600 mV at
