Results for 'acetic acid':
EXPERIMENT 1
---------------
Cobalt (II) forms a coordination complex with nitrous oxide, which easily
decomposes again. On addition of alkali, the cobalt is oxidized and appears
to build a cobalt-compound of an higher oxidation state.
EXPERIMENT 2
---------------
Cobalt carbonate does not dissolve completely in dilute mineral acids. With
some heating, however, it does dissolve completely.
With nitrite a yellow/orange complex is formed, which forms a precipitate
when treated with alkalies. The precipitate is resistant to treatment with
acid and bases.
EXPERIMENT 3
---------------
Ethanol and acetic acid do not form an ester (ethylacetate) when simply
mixed with concentrated sulphuric acid. More extreme conditions are needed
for this reaction to occur.
The acid is diluted too much in order to give a strong reaction with
chlorate, combined with the reducing agent in the form of ethanol.
EXPERIMENT 4
---------------
Niobium pentachloride reacts with acetic acid, giving a colorless fuming gas
(most likely HCl) and a fuming liquid (most likely acetyl chloride).
EXPERIMENT 5
---------------
Ethylacetate is in equilibrium with ethanol and acetic acid, even in dilute
aqueous solution with some free acid in it. Usually, making esters requires
rather forcing conditions, like mixing an alcohol and an organic acid and
adding this mix to concentrated sulphuric acid and then heating the mix. This
experiment nicely demonstrates that there is an equilibrium, also in water.
EXPERIMENT 6
---------------
Formic acid acts as a reductor, while acetic acid does not do so. Formic acid,
however, is not that easily reduced. Reduction requires elevated temperature
and strong oxidizers.
EXPERIMENT 7
---------------
Ethylene glycol does not easily form a hypochlorite ester like ethanol or other
mono-alcohol.
EXPERIMENT 8
---------------
When thiosulfate ion and nitrite ion are brought together in solution, then
nothing happens. When the solution is acidified, then a remarkable reaction
occurs. The liquid then quickly turns dark brown and remains clear. Immediately
after that, a colorless gas is produced and the color becomes lighter. The
color goes from dark brown through brown/orange and yellow to lime green. The
liquid remains clear and lime green for a few minutes and then it slowly
becomes turbid.
EXPERIMENT 9
---------------
The combination of acetyl and sulfate, either directly, or derived from other
compounds reacts extremely energetically with water. It is remarkable that it
is this specific combination of three entities which gives extremely violent
reactions. This effect is demonstrated with different chemicals in different
combinations.
EXPERIMENT 10
---------------
Azide ion reacts with hypochlorite, giving a yellow compound, which is
colorless in the gaseous state. This compound can easily be ignited and
explodes with a really loud report, even when very small quantities are used.
EXPERIMENT 11
---------------
When sodium chlorite solution is acidified with acetic acid, then a brown
solution is obtained, which on addition of more acetic acid becomes lighter and
which on addition of hydrochloric acid becomes bright yellow.
EXPERIMENT 12
---------------
Hypochlorite ion forms esters very easily with alcohols. The esters simply are formed from aqueous
solutions. The methyl ester is a colorless gas, which gives extremely powerful explosions when
ignited. The ethyl ester is a very volatile yellow/green oil, which burns with a WHOOSH sound and
which is quite unstable (it easily decomposes). The t-butyl ester is quite stable and can be kept
around for a somewhat longer time. This burns quickly with a sooty flame.
