Results for 'ammonium thiocyanate':
EXPERIMENT 1
---------------
Cobalt builds complexes with thiocyanate, although not very clearly.
EXPERIMENT 2
---------------
Cobalt builds highly colored complexes with thiocyanate when acetone
is added. This complex is soluble in ether.
EXPERIMENT 3
---------------
Cobalt sulfate dissolves in methanol, albeit not as well as in water. The
liquid obtained is colored quite intensely. The dilute solution of cobalt
sulfate in methanol looks more pink/purple than even the most concentrated
aqueous solution.
With thiocyanate a deep blue complex is formed in methanol.
EXPERIMENT 4
---------------
Ferric ions are reduced by borohydride to a black compound. Is this
metallic iron or is this iron (II) oxide?
EXPERIMENT 5
---------------
Hydroxylamine is capable of reducing ferricyanide to ferrocyanide. On heating,
however, a yellow compound is formed, which apparently is not ferricyanide.
With thiocyanate a pale rose-purple solution is formed on standing. Probably
oxygen from the air also takes part in the reaction.
EXPERIMENT 6
---------------
Copper (II) reacts with thiocyanate in a complex way.
EXPERIMENT 7
---------------
Copper (II) reacts with thiocyanate in a complex way.
EXPERIMENT 8
---------------
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 9
---------------
Copper (II) chloride dihydrate dissolves in ethyl acetate, albeit only
in small amounts. With thiocyanate, a dark coordination complex is formed,
also in ethyl acetate.
EXPERIMENT 10
---------------
A large set of compounds is checked on interaction with concentrated
nitric acid. Many reductors react violently with nitric acid.
EXPERIMENT 11
---------------
Chromium (III) can have many different colors, depending on how it is
created and with which it coordinates.
EXPERIMENT 12
---------------
When chromium (III) is created from dichromate, its color depends on the
reductor used and on the acid which is used for supporting the redox
reaction.
EXPERIMENT 13
---------------
Potassium dichromate dissolves in methanol, albeit not as well as in water.
Potassium chromate hardly dissolves in methanol. When ammonium thiocyanate
is added, then the liquid becomes deep yellow. Is this due to chromate, or
is this some reaction product from the thiocyanate?
EXPERIMENT 14
---------------
Thiocyanate is oxidized by nitrate very violently under the right conditions.
EXPERIMENT 15
---------------
Methanol gives a colorless gas with nitrite in acidic media. No formation
of NO/NO2. This compound probably is CH3ONO, the nitrite ester of methanol.
The large excess of CH3OH does not prevent formation of nitrosyl thiocyanate.
EXPERIMENT 16
---------------
Methanol and nitrate/nitric acid do not react readily, not even at fairly
high temperature (appr. 90C).
EXPERIMENT 17
---------------
Titanium metal slowly dissolves in concentrated hydrochloric acid and then
forms a very dark solution of a titanium/chloride complex. This solution is
much darker than an aqueous solution of titanium(III) in which the ions are
present as aqua complex.
With thiocyanate an even more intensely colored complex is formed. This complex
has the same color, but it is very dark.
