Results for 'Mo':
EXPERIMENT 1
---------------
When molybdates are reduced, then intense blue compounds are formed. It
is believed that these intensely coloured compounds are multi-nuclear
Mo-compounds, with different nuclei having different oxidation states.
EXPERIMENT 2
---------------
In strongly alkaline environments, molybdates are not as easily reduced
as in neutral or acidic environments.
EXPERIMENT 3
---------------
Molybdates and phosphates produce a yellow complex in an anion, containing
both molybdenum and phosphorus. This complex is slowly reduced by sulfite.
EXPERIMENT 4
---------------
Molybdate gives rise to all kinds of complexes, when combined with reducing
agents. These complexes can be yellow, green or blue. The composition of
all these complexes is not very clear.
EXPERIMENT 5
---------------
Molybdate gives a yellow complex with iodide. Order of dissolving and
acidifying has influence on the reactions observed.
EXPERIMENT 6
---------------
Molybdenum trioxide dissolves well in strongly alkaline liquids. It does
not dissolve (or just a little bit) in plain water. Once dissolved, it
can be kept in solution, even when pH is lowered.
Molybdates are capable of oxidizing iodide and sulfite.
EXPERIMENT 7
---------------
Molybdate forms strongly colored, but unstable, complexes with hydrogen
peroxide.
EXPERIMENT 8
---------------
Molybdate forms blue or green compounds, when reduced with mild reducing
agents or when little quantitities of reducing agents are used.
EXPERIMENT 9
---------------
Ammonium molybdate forms a yellow coordination complex with phosphates in
acidic environments, which precipitates. Oxidizing compounds do not
dissolve this precipitate, alkaline compounds do dissolve this precipitate.
EXPERIMENT 10
---------------
Molybdates and orthophosphates give a yellow complex, which is reduced more
easily than molybdates alone.
EXPERIMENT 11
---------------
Phosphates and molybdates are supposed to form a yellow complex. Other
experiments confirm this reaction, but this experiment does not show
such behavior. May be longer heating is required or an excess amount of
a strong acid is required?
EXPERIMENT 12
---------------
When molybdate (VI) is reduced by a small amount of reductor, then a blue
compound is formed. When a larger amount of reductor is available, then a
black compound is formed.
