Results for 'antimony':
EXPERIMENT 1
---------------
Elementary antimony dissolves in aqua regia at a fairly high rate. While
it dissolves a lot of gas is produced. When the liquid is diluted with
water, then a white precipitate is formed, due to hydrolysis of the
reaction product. It looks as if the antimony is oxidized to the +3 oxidation
state.
EXPERIMENT 2
---------------
A clock reaction that precipitates antimony sulfide.
EXPERIMENT 3
---------------
Antimony reacts with iodine, giving antimony triiodide. This reaction, however,
is not very fast and quite a large excess amount of finely powedered antimony
is needed to get all iodine reacted.
Antimony triiodide (SbI3) has quite remarkable properties. Its solution is pale
yellow/green, the solid has a bright orange/red color and the vapor is
colorless or nearly colorless. The liquid (molten) material is yellow.
EXPERIMENT 4
---------------
When antimony is added to liquid bromine, then a violent reaction occurs, even
with appearance of sparks.
