Results for 'stannous chloride':
EXPERIMENT 1
---------------
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.
EXPERIMENT 2
---------------
Palladium (II) is not easily reduced by mild reducing agents. Only very
strong reductors are capable of reducing this to metallic palladium.
Strong oxidizers probably are capable of oxidizing palladium (II) to a
higher oxidation state, but if this is true, then the higher oxidation
state has almost the same color.
Sulfite, instead of reducing palladium to the metallic state, appears to
form a brightly colored coordination complex in acidic environments.
EXPERIMENT 3
---------------
Platinum (II) can be oxidized to platinum (IV) by strong oxidizing agents.
Reduction to metallic platinum cannot be achieved by sulfite nor by stannous
chloride.
EXPERIMENT 4
---------------
Platinum (II) gives a highly coloured compound with tin (II), it is not
reduced to metallic platinum.
EXPERIMENT 5
---------------
Platinum(II) is not reduced by sulfide in acidic environments. When it is
treated with stannous ions at the same time, then a dark brown compound
is formed, but probably this is not metallic platinum but stannous sulfide.
What speaks against this is that stannous chloride does not precipitate
with H2S in acidic environments (see sequence 2), while with the Pt-compound
a dark brown compound is formed. More research will be needed to resolve
this.
EXPERIMENT 6
---------------
Palladium probably gives a very finely divided metallic compound, when it is
reduced by stannous chloride. The intense colors, appearing in this
experiment probably are caused by colloidal solutions.
EXPERIMENT 7
---------------
Tin (II) compounds forms either a yellow or orange/red compound with
iodides. What compound is formed, depends on the concentration of the
reactants.
At very low pH such a compound is not formed anymore, and once formed,
it can be dissolved.
EXPERIMENT 8
---------------
Dichromate is quickly reduced by tin (II) ions.
Hydrogen peroxide does not show a visible reaction with tin (II) ions.
EXPERIMENT 9
---------------
Arsenic in oxidation state +5 is not easily reduced to elemental arsenic,
except by tin(II) chloride.
EXPERIMENT 10
---------------
Rhenium forms complexes with thiocyanate in more than one oxidation state.
Here a rhenium (IV) thiocyanate complex is made and then oxidized to rhenium
(V). Historically these complexes have been used to detect minute traces of
rhenium due to the intense colours formed.
EXPERIMENT 11
---------------
Arsenic in oxidation state +3 is quickly reduced to elemental arsenic by
tin(II) chloride in hydrochloric acid.
