Abstract

Bubbles produced at an electrode in an electrolytic process are coalesced by providing a surface-limiting, electrically inert masking device of which at least a bottom portion is submerged in the electrolyte. The masking device reduces the free surface of the electrolyte between the electrodes and this urges the gas bubbles together so that they coalesce, resulting in larger bubbles and less acid mist generation.
