Results for 'iodine':
EXPERIMENT 1
---------------
This experiment is performed in order to determine, whether iodoform (CHI3)
shows a reaction, similar to chloroform, when treated with acetone in a
strongly alkaline environment. The result of this experiments suggests
that indeed a similar reaction occurs, resulting in the formation of a
compound with a sweetish mint-like odour.
EXPERIMENT 2
---------------
Ammonia reacts with iodine, giving nitrogen iodide, coordinated to ammonia.
When acetone is present, however, then a so called haloform reaction
occurs, resulting in formation of CHI3.
EXPERIMENT 3
---------------
Iodine dissolves in thionyl chloride. It does not react. It gives a purple
solution, looking very similar to a purple solution of iodine in an alkane or
chlorinated hydrocarbons.
When water is added, then a remarkable reaction occurs. Sulphur is formed.
EXPERIMENT 4
---------------
Iodine does not react with nitrite in methanolic solution.
Iodine does react with hydroxide in methanolic solution, a very light yellow
compound is formed. On acidification this gives iodine again.
Iodine does react with red phosphorous in methanolic solution, but the reaction
is slow.
EXPERIMENT 5
---------------
Iodine dissolves somewhat in chlorosulfonic acid with a brown color.
EXPERIMENT 6
---------------
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.
