Results for 'Hg':
EXPERIMENT 1
---------------
Mercury (II) ions produce a bright orange colored precipitate with iodide.
EXPERIMENT 2
---------------
Mercury (II) salts give an oxide/hydroxide, which does not dissolve in
large excess amounts of alkaline solutions. Ammonia does not dissolve
the precipitate of mercury (II) oxide/hydroxide.
EXPERIMENT 3
---------------
This is a very nice experiment, involving beautifully coloured compounds,
but it is a hazardous experiment as well, due to the use of mercury (II)
compounds.
Mercury (II) builds a complex with excess iodide, [HgI4]2-, which gives a
beautiful bright yellow precipitate with Ag+ and a beautiful bright brick-
red precipitate with Cu+.
EXPERIMENT 4
---------------
Mercurous ions are stable in aqueous solution at room temperature. They do not
hydrolyse, nor disproportionate.
However, when a compound is added, with which a stable mercury(II) complex is
formed, or with which a stable mercury(II) precipitate is formed, then the
mercury(I) disproportionates to the metal and mercury(II).
