Samenvatting

Water electrolysis with a fast change of the polarity pumps in the liquid a huge amount of hydrogen and oxygen gases. In contrast with the DC electrolysis the gases do not form visible bubbles but change significantly the refractive index of the liquid nearby the electrodes from n = 1.35 to the values smaller than 1.19. The decrease of n is registered as distortion of the images of the electrodes. We argue that all the gas is collected in H2 and O2 nanobubbles with a size smaller than 200 nm. The concentration of nanobubbles with a size of 100 nm is estimated as 1021 m-3. Due to a significant contribution from the Laplace pressure the effective supersaturation reaches 500 for hydrogen and 150 for oxygen.
