A generation of hydrogen and oxygen bubbles by of aqueous solutions of electrolytes was carried out. Two electrolysis modifications was study: electrolysis without a membrane to production of oxygen and hydrogen and membrane electrolysis with separation of catholyte and anolyte. The influence of the model conditions of the experiment such as electrolyte pH, concentration, and current density and the distribution of bubble sizes and gas holdup in the column are discussed. An inverse dependence of the hydrogen bubbles diameter in the catholyte medium on the current density and a direct dependence on the concentration of electrolytes are experimentally investigated. The oxygen bubbles tend to become larger with increasing current density and electrolyte concentration in anolyte medium. In electrolysis without a membrane, bubbles become smaller with increasing current density and decreasing the electrolyte concentration.
