Reply to “Comment on ‘Negative Deviations from the Debye–Hückel Limiting Law for High-Charge Polyvalent Electrolytes: Are They Real?’ ”

In their “Comment on ‘Negative Deviations from the Debye–Hückel Limiting Law for High-Charge Polyvalent Electrolytes: Are They Real?’ ” Biver and Malatesta, citing my respective paper, argue that my analysis of experimental data of their group is wrong and so is my conclusion that negative deviations observed by them are not physically real. Here I rebut their arguments and explain why their rejection of my work is unjustified, and why those authors do not in any way prove me wrong. The core of my study and conclusion remains intact: Negative deviations in the case of high-charge electrolytes with |z+z–| > 3 do not always happen, and so far, such observed deviations are not convincingly supported by theory.
