Results for 'sodium chloride':
EXPERIMENT 1
---------------
Copper (II) is reduced by sulfite. With chloride the resulting copper (I)
can be kept in solution. The copper (I) compound is very susceptible
to oxidation by oxygen from the air.
EXPERIMENT 2
---------------
Copper (II) chloride reacts violently with metallic aluminium. When copper
sulfate or nitrate is used, then this reaction does not occur. When sodium
chloride is used, this reaction also does not occur. Both cupric ions and
chloride ions are needed for quick reaction with aluminium, but if they are
present, then a very violent reaction occurs.
EXPERIMENT 3
---------------
Copper (II) chloride dissolves in fairly concentrated nitric acid, but it does
not dissolve easily. Only a small amount can be dissolved. It dissolves with
a bright green/cyan color. Aluminum metal is not attacked by this solution.
Slight dilution does not make the liquid more active towards aluminum. When a
lot of sodium chloride is added, then the aluminum is attacked and it
dissolves.
EXPERIMENT 4
---------------
Nitrite forms a dark green coordination complex with copper (II) ions in
neutral environments. When acidified, then a new coordination complex
(dark blue with a grey hue) is formed in the presence of chloride of
very high concentration. This is not formed when chloride is absent.
EXPERIMENT 5
---------------
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 6
---------------
Palladium (II) is not oxidized by H2O2 in acidic environments.
EXPERIMENT 7
---------------
Palladium (II) is not easily reduced by mild reducing agents. Only very
strong reductors are capable of reducing this to metallic palladium.
Strong oxidizers probably are capable of oxidizing palladium (II) to a
higher oxidation state, but if this is true, then the higher oxidation
state has almost the same color.
Sulfite, instead of reducing palladium to the metallic state, appears to
form a brightly colored coordination complex in acidic environments.
EXPERIMENT 8
---------------
Palladium probably gives a very finely divided metallic compound, when it is
reduced by stannous chloride. The intense colors, appearing in this
experiment probably are caused by colloidal solutions.
EXPERIMENT 9
---------------
Aluminum reacts vigorously with water, when its passivating layer of oxide
is effectively destroyed. This can be achieved by using tetrachloro or
tetrabromo complexes of copper (II).
Acid can also be used to destroy the passivating layer, but this takes
considerably more time.
Cobalt has a similar effect as copper (II), but it is less pronounced.
EXPERIMENT 10
---------------
Bismuth (III) forms a deep-orange iodo-complex and a yellow iodo-chloro
complex.
EXPERIMENT 11
---------------
Sodium chloride reacts with sulfuric acid to give hydrogen chloride gas.
Sodium bromide shows a similar reaction, producing hydrogen bromide, but
in a side reaction some bromine is formed.
EXPERIMENT 12
---------------
Sodium chlorate reacts with chloride in acidic environment, forming chlorine
(which can be detected by means of its odour) and a fairly intensely colored
yellow gas (chlorine dioxide). The color of this gas is much more intense
than the color of chlorine.
The yellow compound is destroyed by sulfite and nitrite.
EXPERIMENT 13
---------------
Bromate reacts with chlorides, releasing chlorine. Probably some bromine
is produced as well or a bromine/chlorine compound is produced.
EXPERIMENT 14
---------------
TCCA does not react with sulphuric acid, at least not visibly. Even when
heated, no reaction seems to occur. On addition of some solid NaCl vigorous
evolution of chlorine gas is observed.
EXPERIMENT 15
---------------
Praseodymium (III) ions form complexes with chloride, bromide and iodide. With
fluoride a precipitate is formed.
EXPERIMENT 16
---------------
Hexavalent chrome forms a stable volatile compound, when mixed with chloride
in strongly dehydrating conditions. The compound formed is called chromyl
chloride and its constitution is CrO2Cl2.
EXPERIMENT 17
---------------
Chromium (III) builds a nice brightly colored green complex with phosphates.
This compound has no bluish hue, like sulfate gives with chromium (III).
Chloride also builds a complex. Formation of these complexes is not on
simple addition of a chromium (III) salt to the corresponding anions.
Heating is required.
EXPERIMENT 18
---------------
When ethanol and acetone are mixed, together with sulphuric acid, then no
special visible reaction occurs. The compounds are bound to the acid. Their
smell hardly exists after mixing with the acid.
The mixture is not capable anymore of producing HCl from NaCl, nor does it
show a strong reaction with KMnO4 (as was expected, due to the presence of
concentrated H2SO4).
