Abstract
IN 1907 Fischer and Massenez (Z. anorg. Chem., 52, 202, 1907) obtained a concentration of 17 per cent. by weight of ozone when they electrolysed a solution of sulphuric acid, using a very high current density. Since ozone can be produced by this method, it would seem probable that a high current density at the cathode might aid in producing the ozone form of hydrogen. When a solution of sulphuric acid is electrolysed, using the above principle, the hydrogen that escapes at the cathode contains an active con stituent which combines with pure nitrogen to form ammonia. Some of the ammonia formed is collected in the absorption bulb, but quite a large portion of it remains dissolved in the sulphuric acid solution. This active constituent in the hydrogen that is evolved at the cathode is probably the ozone form, and is produced perhaps in a manner analogous to the ozone form of oxygen. The per cent. of the active gas formed varies with the current density and the concentration of the acid.
