Description of experiment
Below follows a plain text transcript of the selected experiment.
Needed compounds:
-----------------
hydrogen peroxide : H2O2
hydrochloric acid : HCl
sodium chloride : NaCl
palladium chloride : PdCl2
Class:
------
elem=Pd
redox
Summary:
--------
Palladium (II) is not oxidized by H2O2 in acidic environments.
Description:
------------
Add some PdCl2 to an excess amount of a solution of NaCl: The PdCl2 dissolves
and the resulting liquid is clear and brown.
Add some hydrochloric acid (appr. 10% by weight) to the brown liquid: No
visible changes.
Add some hydrogen peroxide (appr. 10% by weight): No visible changes.
Heat the liquid: A lot of oxygen is produced, the color of the liquid, however,
does not change.
