Results for 'bleach':
EXPERIMENT 1
---------------
Sulfide gives precipitates with some metals, which do not dissolve in
strong acids. These sulfides, however, can easily be dissolved, when an
oxidizing agent is used.
Sulfide is easily oxidized by moderately strong oxidizers.
EXPERIMENT 2
---------------
When p-aminophenol is oxidized by hypochlorous acid, then an other oxidation
product is formed, compared to oxidation by e.g. persulfate, hydrogen
peroxide etc. When oxidized by hypochlorous acid a yellow solid compound
is formed, otherwise an intense indigo/purple compound is formed, which
remains dissolved.
EXPERIMENT 3
---------------
P-aminophenol HCl reacts with bromine and forms a purple compound.
EXPERIMENT 4
---------------
Bromide is oxidized by sulphuric acid, even when diluted with water.
Bromine precipitates from water, when it is created in high concentrations.
EXPERIMENT 5
---------------
Chlorine reacts with acetylene gas (C2H2), without the need to ignite it.
EXPERIMENT 6
---------------
A large set of compounds is checked on interaction with concentrated
nitric acid. Many reductors react violently with nitric acid.
EXPERIMENT 7
---------------
Bleach is capable of oxidizing chromium (III) to its hexavalent state, but
this is not accomplished easily and completely.
EXPERIMENT 8
---------------
Bleach is not capable of oxidizing ferric hydroxide to the hexavalent
ferrate (at least not at 60 C within several minutes).
EXPERIMENT 9
---------------
Ferric chloride reacts with bleach and forms a brown precipitate. No
higher oxidation products of iron can be observed.
EXPERIMENT 10
---------------
Nickel in nickel (II) hydroxide is oxidized to a higher oxidation state by
hypochlorites, but not by chlorates. The oxidation product is reduced by
hydrogen peroxide and ammonia. Heating of the oxidation product makes it
more resistant to reduction and to breakdown by acids.
EXPERIMENT 11
---------------
Red phosphorus dissolves in concentrated sulphuric acid, when it is strongly
heated.
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.
EXPERIMENT 13
---------------
Formation of hypochlorite esters is very easy. With many alcohols, it is
possible to make hypochlorite esters. These esters are very unstable and easily
explode or burn very fiercely when ignited.
All experiments, described here are quite dangerous, use good protection of the
eyes and keep test tubes wrapped in a thichk layer of towels. Do not scale up!
EXPERIMENT 14
---------------
Ethylene glycol does not easily form a hypochlorite ester like ethanol or other
mono-alcohol.
EXPERIMENT 15
---------------
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 16
---------------
White phosphorus reacts with hot solutions of sodium hydroxide and gaseous
phosphine and diphosphine are produced. The diphosphine spontaneously combusts
in air, the phosphine does not. The diphosphine is very unstable and within a
few minutes it reacts and only phosphine is left.
REMARK: THIS IS A VERY DANGEROUS EXPERIMENT. WHEN NOT CARRIED OUT WITH
SUFFICIENT PRECAUTIONS. KNOW WHAT YOU ARE DOING!!
