The effect of different inert salts on the buffer indicator equilibrium sodium acetate+acetic acid+ bromcresol green has been investigated by a differential spectrophotometric method. The results can be represented on the basis of the modified Debye-Huckel equation proposed by Guggenheim and Schindler. The tetra-alkylammonium salts behave very differently from the other salts. The differences between the salt effects on this equilibrium and the kinetic salt effects on some reactions between two monovalent anions are discussed. Although the presence in this equilibrium of a neutral molecule may have some influence, it seems that the main cause of these differences consists in the catalytic character of the action that cations often have on reactions between anions.
