Ion-Specific Coalescence of Bubbles in Mixed Electrolyte Solutions

Henry, Christine; Dalton, Casuarina; Scruton, Le Hoa; Craig, Vincent


Ion-specificity is at the heart of many biological processes and is important in all soft-matter systems at high electrolyte concentrations. The effect of electrolytes on bubble coalescence in water is a simple example of ion-specificity. Single electrolytes inhibit coalescence or have no effect, as predicted by ion-combining rules based on empirical assignments (α or β). The mechanism behind electrolyte inhibition, as well as the salt differentiation, is not understood. We here report that...[Show more]
