Abstract
The invention relates to a process for the electrolytic generation of arsine from an electrochemical cell provided with a cathode supplied with H.sup.+ and AsO.sub.2.sup.- ions where two concurrent reactions take place producing arsine and gaseous hydrogen respectively, and an anode where a reaction producing H.sup.+ ions takes place, the ratio of the H.sup.+ /As concentrations at the cathode being controlled and kept constant.
