Abstract : We respond to recent criticism (R. D. Armstrong, J. Electroanal. Chem. 372 (1994) 27) of our earlier paper on the admittance of the needle peak of tetrabutyl ammonium bromide at the mercury-water interface (J. Electroanal. Chem., 352 (1993) 279), and pinpoint areas of serious misunderstanding. In a series of papers 1-3 we have reported on the adsorption behavior of tetrabutylammonium ions at the mercury-water interface, a system studied earlier by a variety of workers. (For extensive references to those earlier studies see 1). The third of these papers examined the admittance of the so-called needle peak, a sharp and narrow capacitance peak, which was first reported by Frumkin et al. 4. We presented experimental results, and a theoretical model that qualitatively explains the main features of these results 3. In a recent communication 5, Dr. Armstrong takes issue with the adequacy of the data we reported, and with the validity of our theoretical model. Both the substance and vehemence of his objections require that we reply to Dr. Armstrong's comments. jg p.3
