Results for 'sodium cyanide':
EXPERIMENT 1
---------------
Hydrogen cyanide (or cyanide salt) slowly changes to a dark brown/black
compound, when it is allowed to stand. At least this happens in strongly acidic
media.
EXPERIMENT 2
---------------
Copper sulfate dissolves in methanol quite well. A blue solution is obtained.
Copper chloride dihydrate also dissolves in methanol quite well. A green
solution is obtained.
With thiocyanate a deep brown complex is formed, which dissolves in
methanol, but at higher concentration this precipitates.
With cyanide, a dirty green compound is formed, which, however, quickly
turns white. This probably is copper (I) cyanide.
EXPERIMENT 3
---------------
Copper (II) forms a yellow/brown coordination complex with cyanide in
acidic media in the presence of chloride.
EXPERIMENT 4
---------------
Rhenium, when dissolved in nitric acid, gives colorless perrhenate ions,
[ReO4]-. With zinc, in the presence of hydrochloric acid of sufficient
concentration, this can be reduced to a yellow/green species. With cyanide,
in alkaline environment this forms a brown and clear solution. The yellow/
green species may be [ReCl6]2-, which according to literature is green.
With cyanide, a complex may be formed.
EXPERIMENT 5
---------------
Cyanate ion forms complexes with many metal ions. These complexes have a strong
color and are not stable in acidic solution.
