Ammonium heptasulphide

Ammonium heptasulphide, (NH4)2S7— J. Fritzsche reported that crystals of this salt are formed by the spontaneous vaporization of crystals of the penta-snlphide melting crystals of the pentasulphide in their own mother liquid, and... [Pg.653]

Under these conditions W. P. Bloxam obtained crystals of sulphur and of the pentasulphide, but no ruby-red crystals of the heptasulphide, and he obtained the enneasulphide by working according to J. Fritzsche s directions. P. Sabatier claims to have made the heptasulphide by digesting sulphur with the warm or cold mother liquid remaining after the separation of crystals of the pentasulphide. P. Sabatier s analysis corresponds with ammonium octomlpkide, (NH Sg. W. P. Bloxam made crystals of the hydrated salt, (NH4)2S7.fH20, by the simultaneous action of sulphur and hydrogen sulphide on aqua ammonia rather more cone, than that used in the preparation of the pentasulphide. [Pg.654]

As previously indicated, when W. P. Bloxam attempted to make ammonium disulphide, he obtained crystals which, when rapidly dried between filter paper gave analytical numbers corresponding with tetrahydrated tetrammonium heptasulphide, (NH4)jS,.4HaO, but there... [Pg.651]
