✦ Synopsis

The halides have received particular attention in the study of the electrical double layer. In the absence of a second electrolyte, their adsorption increases from the fluoride ion to the strongly adsorbed iodide ion. It has been believed that the fluoride ion is not specifically adsorbed, though recently claims to the contrary have been made 1. The adsorption of the chloride, bromide, and iodide ions from solutions containing their sodium or potassium salts is qualitatively similar 2 4. This is not the case when the same ions are adsorbed from systems which may be represented as xM KX + (l-x) M KF where X is either iodide or chloride 5'6. The significant differences observed in these two systems suggested that the study of the bromide system was desirable.
