We report on bubble coalescence inhibition by non-surface-active, nonelectrolytes urea and sucrose, and other small sugars, in aqueous solution. Urea has no effect on bubble stability up to high concentrations>1 M, while sucrose inhibits coalescence in the range 0.01-0.3 M, similar to inhibiting electrolytes. Urea and sucrose both increase bubble coalescence inhibition in inhibiting and noninhibiting electrolytes in a cooperative manner, but urea decreases the efficacy of sucrose in mixed...[Show more]
