Silvery metal. Tarnishes in air, soluble in acids but not alkalis. Used
in rechargeable batteries, alloys, pigments.
Diagnostic tests:
On charcoal with soda (Na2CO3), compounds of cadmium
give a characteristic sublimate of the reddish brown oxide.
In solution, the addition of Na2S or (NH4)2S
produces a bright yellow precipitate of CdS (School Bus yellow).
