Schlippe's Salt

SCHLIPPE'S SALT, or sodium thioantimoniate, NajSbS^QHjO, named after K. F. Schlippe (1799-1867), is prepared by dissolving the calculated quantities of antimony trisulphide, sulphur and sodium hydroxide in water, or by fusing sodium sulphate (16 parts), antimony sulphide (13 parts) and charcoal (4-5 parts), dissolving the melt in water and boiling the solution with 2 parts of sulphur. The liquid is then filtered and evaporated. The salt crystallizes in large tetrahedra, which are easily soluble in water, and have a specific gravity 1-806. The anhydrous salt .melts easily on heating, and in the hydrated condition, on exposure to moist air becomes coated with a red film. It combines with sodium thiosulphate to form Na 3 SbS 4 -Na 2 S 2 O 3 -2OH 2 O.
