摘要：
It is experimentally established that, in the course of bubbling of "passive" gases through the aqueous solutions of NaCl, we observe not only the wash-out of soluble CO2 and O-2 but also the continuous generation a new gas-solution interface, which has a pronounced acid character. This is why bursting of gas bubbles on the surface is accompanied by the formations of acid aerosols and the appearance of a specific bubbling chemical effect (BCE), when the pH value of the solution independently increases (alkaline BCE) or decreases (acid BCE). The form of the BCE is determined by the type of aerosol (finely or coarsely divided) and the rate of its removal from the system. In distilled water, the BCE is not observed. Structural changes in water may serve as a cause of the acidity of interface in gas bubbles.
