Results for 'Cd':
EXPERIMENT 1
---------------
Cadmium selenide reacts vigorously with nitric acid, producing nitrous
fumes and a yellow/orange solid, which is filled with many small gas bubbles
and hence remains floating on the liquid.
Cadmium sulfide gives a similar reaction, but now a pale yellow solid is
formed. This yellow solid is sulphur.
EXPERIMENT 2
---------------
Cadmium ions give a precipitate with sulfide at very low concentration
of free sulfide ions. Only at very low pH, cadmium ions and hydrogen
sulfide can coexist in solution at appreciable concentration.
A very similar effect can be seen with combinations of cadmium and
selenide.
