A number of authors have investigated the chemical processing due to fission of collapsing bubbles. In the present study, we focus on a venturi type microbubble generator. In this generator, rapid shrinkage and the collapse of bubble are generated. The purpose of the present study is to clarify the possibility of the chemical reaction in the venturi type microbubble generator. The chemical reaction was examined from pH, electric conductivity and gas concentration measurement because CO2 gas which changes pH, electric conductivity and CO2 gas concentration of solvent is expected to generate in the present chemical reaction. In order to identify the bubble breakup, we observed bubbly flow behavior in the venturi tube. Consequently, the difference of change of pH value, electric conductivity and CO2 gas concentration were obtained by rapid bubble breakup.
