Results for 'phosphorus red':
EXPERIMENT 1
---------------
Chlorite ion forms complexes with cobalt(II) and copper(II). It forms a
precipitate with lead(II). The precipitate with lead(II) forms a highly
energetic compound.
EXPERIMENT 2
---------------
Red phosphorus dissolves in concentrated sulphuric acid, when it is strongly
heated.
EXPERIMENT 3
---------------
The yellow pigment aureolin, also known as cobalt yellow, and having the
chemical name potassium hexanitrito cobaltate(III), can be used as a mild
oxidizer which gives a very smoothly and evenly burning mix with red
phosphorus. When also aluminium powder is added to the mix, then the reaction
is more violent and sparks are sprayed around.
EXPERIMENT 4
---------------
Potassium bromate reacts with aluminium powder with a very bright light and
with crackling noise, but the mix is not like flash powder. Some sulphur is
needed for easy ignition of the mix.
When a tiny amount of red phosphorus is added to the mix, then it is ignited
even more easily, but then it also burns exceptionally fast, almost
explosively.
EXPERIMENT 5
---------------
A mix of potassium perchlorate and sulphur cannot easily be ignited. When just
a tiny pinch of red phosphorus is mixed in, then the mix is ignited very easily
and it burns very fast with a bright flash.
EXPERIMENT 6
---------------
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!!
EXPERIMENT 7
---------------
This is a spectacular experiment. A mix of sodium chlorite and red phosphorus
can be ignited by bringing it in contact with hydrochloric acid.
EXPERIMENT 8
---------------
Vanadium pentoxide does not seem to react with red phosphorus.
EXPERIMENT 9
---------------
Powdered magnesium and powdered red phosphorus react violently, when heated
sufficiently. The reaction product contains considerable amounts of magnesium
phosphide.
EXPERIMENT 10
---------------
Silver chlorite is stable, but only light heating is required for its
decomposition.
