Abstract
EVIDENCE for the formation of active hydrogen from its positive ion in an acid has been negative. The reports of the latest workers in this field, Wendt and Landauer (Jour. Amer. Chem. Soc. 42, 930 : 1920) show that there are certain difficulties to be met. The main one is to eliminate the moisture that accompanies a rapid evolution of hydrogen and at the same time not to destroy the active hydrogen if any were formed. If the velocity of the gas stream were too low, the active component would decay before reaching the sulphur. Then if the velocity were too high the moisture carried over would form a protecting film on the powdered sulphur and prevent the reaction between the two to form hydrogen sulphide.
