Results for 'phosphoric acid':
EXPERIMENT 1
---------------
Iron (III) builds a coordination complex with phosphates.
EXPERIMENT 2
---------------
In concentrated phosphoric acid, manganese (II) ions are oxidized easily to
manganese (III) ions, which are stabilized by formation of a phosphato-complex
with a remarkably bright purple color. This reaction is remarkable in the sense
that oxidation stops at manganese (III).
EXPERIMENT 3
---------------
Copper (II) does not form a coordination complex with phosphates and/or
phosphoric acid.
EXPERIMENT 4
---------------
When phosphoric acid is mixed with water, then some heat is produced, but
this is much less than the heat, produced on mixing water with sulphuric
acid.
EXPERIMENT 5
---------------
Phosphoric acid is not capable of driving off hydrogen bromide from
alkali bromides, nor does it oxidize bromide.
EXPERIMENT 6
---------------
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 7
---------------
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.
