Abstract
The charging of hydrogen, oxygen, and carbon dioxide gas bubbles in va rious electrolytes was studied by measuring the bubble rise potential. The gas bubbles acquire a negative charge whose magnitude is determin ed by the zeta-potential and by the hydrodynamic and diffusion phenome na on the bubble surface and in the electrolyte. Limitations of the pr oposed method of charge evaluation at the gas-solution interface are c onsidered.
