The possible molecular mechanisms of water structuring and between the surfaces of gas/water in the solutions are considered. It was shown that barbotage activation (BA) occurs by increasing the structural temperature of water and causes increasing of chemical activity of H2O and dissolved oxygen. It is established that BA has quasi equilibrium character. Therefore external influences on the lines of changes of pH and Eh characteristic peaks or steps appear that can be used to investigate the interaction of solutions with different solid materials. The proposed model of structural transformation may explain why negatively charged bubbles of gas form positively charged droplets of sea spray.

Keywords: salt solutions, barbotage of passive gases, structural temperature of water, structural activation, structural quasi equilibrium, chemical resistance of metals.
