(3) on charcoal. Fuses and is partly absorbed by the charcoal and partly volatilized, incrusting the charcoal with the characteristic white oxides. Colors the flame blue.
(7) with carb. soda. Fuses and is reduced, yielding metallic antimony, which behaves as the preceding mineral upon charcoal. The alkaline mass gives the sulphur reaction.
(1) in glass-bulb. Fuses easily, gives off first SbO^{ 3} and afterwards an orange colored sublimate. Strongly heated, is decomposed and gives a black sublimate, which becomes brown on cooling.
(8) Special reactions. As native antimony.
(1) in glass-bulb. Is sublimed and recondensed in the neck of the tube.
(3) on charcoal. Fuses with the evolution of dense white fumes, which incrust the surface of the charcoal. In the reducing flame is partly reduced, yielding metallic antimony. Colors flame blue.
(4) in forceps. Fuses and is volatilized, coloring the outer flame blue.
(5) in borax. Gives the antimony reaction.
(7) with carb. soda. In the reducing flame is reduced, yielding metallic antimony.
(8) Special reactions. As native antimony.
(1) in glass-bulb. Sublimes without fusion and recondenses as a dark grey metallic sublimate, sometimes leaving a small residue.
(2) in open tube. If gently heated in a good current of air passes off as AsO^{ 3}, which is partly condensed as a white sublimate in the upper part of the tube.
(3) on charcoal. Passes off as AsO^{ 3}, which thinly incrusts the charcoal beyond the assay.
(1) in glass-bulb. Fuses, enters into ebullition and is sublimed as a transparent red sublimate.
(2) in open tube. Gently heated passes off as SO^{ 2} and AsO^{ 3}, the latter of which is redeposited in the upper part of the tube.
(3) on charcoal. Fuses and passes off as arsenious and sulphurous acids.
(4) in forceps. Fuses and colors the flame blue.
(7) with carb. soda. As on charcoal, except that the S combines with the alkali forming NaS, which on silver gives the sulphur reaction.
(1) in glass-bulb. As the preceding, except that the sublimate is of a dark yellow color when cold.
(1) in glass-bulb. Sublimes without fusion and re-condenses in white crystals.
(3) on charcoal. Sublimes and is partly recondensed on charcoal forming a white incrustation.
